IgG1 (human) Matched Antibody Pair Reference: REV-31-1019-MK The Human IgG1 Matched Antibody Pair recognize Human IgG1 specifically and does not cross-react to IgG from Non-Human Primate species (Rhesus and Cynomologus macaques), or mouse, rat, goat immunoglobulin. This Human IgG1 Matched Antibody Pair can be used for the detection of therapeutic antibodies from samples obtained from experimental animals to provide accurate pharmacokinetic (PK) data.IgG (Immunoglobulin G) is the most abundant Ig isotype in serum and makes up approximately 75% of all serum Immunoglobulins. In humans, there are four subclasses of IgG with highest serum concentrations of IgG1 followed by IgG2, IgG3 and IgG4. The IgG molecule consists of two heavy and two lights chains (kappa or lambda) resulting in a molecule with two arms for antigen binding. High levels of IgG antibodies are induced following the initial IgM response in a typical immune response to antigens. Because of its relative abundance and excellent specificity toward antigens, IgG is the principle antibody used in immunological research and clinical diagnostics. Clinically, measured IgG antibody levels are generally considered to be indicative of an individual's immune status to particular pathogens.
IgG2 (human) Matched Antibody Pair Reference: REV-31-1020-MK The Human IgG2 Matched Antibody Pairs is specific to Human IgG2 and has been demonstrated through ELISA to not recognize (cross) IgG from Non-Human Primate species (Rhesus and Cynomologus macaques), nor does the matched pair recognize mouse, rat or goat immunoglobulin.

IgM (human) Matched Antibody Pair Reference: REV-31-1023-MK The Human IgM Matched Antibody Pairs is specific to Human IgM and has been demonstrated through ELISA. It does not cross-react to IgG from Non-Human Primate species (Rhesus and Cynomologus macaques), or mouse, rat or goat immunoglobulin. The kit can be used for the detection of therapeutic antibodies from samples obtained from experimental animals to provide accurate pharmacokinetic (PK) data.Immunoglobulin M (IgM) is one of several isotypes of antibody (also known as immunoglobulin) that are produced by vertebrates. IgM is the largest antibody, and it is the first antibody to appear in the response to initial exposure to an antigen. In the case of humans and other mammals that have been studied, the spleen, where plasmablasts responsible for antibody production reside, is the major site of specific IgM production.
IgE (human) Matched Antibody Pair Reference: REV-31-1024-MK The Human IgE Matched Antibody Pairs is specific to Human IgE and has been demonstrated through ELISA. It does not cross-react to IgG from Non-Human Primate species (Rhesus and Cynomologus macaques), or mouse, rat or goat immunoglobulin. The kit can be used for the detection of therapeutic antibodies from samples obtained from experimental animals to provide accurate pharmacokinetic (PK) data.Immunoglobulin E (IgE) is an antibody isotype that has only been found in mammals. IgE is synthesized by plasma cells. Monomers of IgE consist of two heavy chains (epsilon chain) and two light chains, with the epsilon chain containing 4 Ig-like constant domains (Cepsilon1-Cepsilon4). IgE's main function is immunity to parasites such as helminths or certain protozoan parasites such as Plasmodium falciparum. IgE may have evolved as a last line of defense to protect against venoms. IgE also has an essential role in type I hypersensitivity, which manifests in various allergic diseases, such as allergic asthma, most types of sinusitis, allergic rhinitis, food allergies and atopic dermatitis. IgE also plays a pivotal role in responses to allergens, such as: anaphylactic reactions to drugs, bee stings and antigen preparations used in desensitization immunotherapy.
IgD (human) Matched Antibody Pair Reference: REV-31-1025-MK The Human IgD Matched Antibody Pairs is specific to Human IgD and has been demonstrated through ELISA. It does not cross-react to IgG from Non-Human Primate species (Rhesus and Cynomologus macaques), or mouse, rat or goat immunoglobulin. The kit can be used for the detection of therapeutic antibodies from samples obtained from experimental animals to provide accurate pharmacokinetic (PK) data.Immunoglobulin D (IgD) is an antibody isotype that makes up about 1% of proteins in the plasma membranes of immature B-lymphocytes where it is usually co-expressed with IgM. IgD is also produced in a secreted form that is found in very small amounts in blood serum, representing 0.25% of immunoglobulins in serum. Secreted IgD is produced as a monomeric antibody with two heavy chains of the delta (delta) class, and two Ig light chains. In B cells, the function of IgD is to signal the B cells to be activated. By being activated, B cells are ready to take part in the defense of the body as part of the immune system. IgD was found to bind to basophils and mast cells and activate these cells to produce antimicrobial factors to participate in respiratory immune defense in humans. It also stimulates basophils to release B cell homeostatic factors.
IgA (human) Matched Antibody Pair Reference: REV-31-1030-MK The Human IgA Matched Antibody Pairs is specific to Human IgA and has been demonstrated through ELISA. It does not cross-react to IgG from Non-Human Primate species (Rhesus and Cynomologus macaques), or mouse, rat or goat immunoglobulin. The kit can be used for the detection of therapeutic antibodies from samples obtained from experimental animals to provide accurate pharmacokinetic (PK) data.Immunoglobulin A (IgA) is an antibody isotype that plays a crucial role in the immune function of mucous membranes. IgA has two subclasses (IgA1 and IgA2) and can be produced as a monomeric as well as a dimeric form. The IgA dimeric form is the most prevalent and is also called secretory IgA (sIgA). sIgA is the main immunoglobulin found in mucous secretions, including tears, saliva, sweat, colostrum and secretions from the genitourinary tract, gastrointestinal tract, prostate and respiratory epithelium. It is also found in small amounts in blood. The secretory component of sIgA protects the immunoglobulin from being degraded by proteolytic enzymes; thus, sIgA can survive in the harsh gastrointestinal tract environment and provide protection against microbes that multiply in body secretions. In the blood, IgA interacts with the Fc receptor called FcalphaRI (or CD89), which is expressed on immune effector cells, to initiate inflammatory reactions.
25-OH Vitamin D3 Matched Antibody Pair Reference: REV-31-1315-MK The 25-OH Vitamin D3 Matched Antibody Pair is specific to 25-OH Vitamin D3 and has been demonstrated through ELISA. It does not cross-react with Vitamin D3, Vitamin D2, and 25-OH Vitamin D2. This kit includes capture and detection antibodies. 25-Hydroxyvitamin D3 is produced in the liver by 25-hydroxylation of cholecalciferol or Vitamin D3. It is a precursor for other Vitamin D3 metabolites and has only a limited biological activity in itself. Detection of 25-Hydroxyvitamin D3 is important for the diagnosis of Vitamin D deficiency, insufficiency or intoxication.
LAIR2 (human) Matched Antibody Pair Reference: REV-31-1371-MK LAIR-2 (CD306) is a secreted/soluble receptor, mainly produced by CD4+ T-lymphocytes, and is able to regulate the inhibitory potential of LAIR-1. Both LAIRs have been associated with several autoimmune diseases and inflammatory responses.
5-Methylcytosine (5-mC) DNA Matched Antibody Pair Reference: REV-31-1110-MK 5-Methylcytosine is a methylated form of the DNA base cytosine that regulates gene transcription and is involved in epigenetics. It is one of the best known epigenetic modifications. This methylation typically occurs at cytosine in CpG dinucleotides in vertebrates. When cytosine is methylated, the DNA maintains the same sequence, but the expression of methylated genes can be altered. 5-Methylcytosine is a very important repressor of transcription in the genome. When present in promoters, 5-Methylcytosine is associated with stable, long-term transcriptional silencing. This may occur by either blocking positive transcription factors, or promoting the binding of negative ones.
5-Hydroxymethylcytosine (5-hmC) DNA Matched Antibody Pair Reference: REV-31-1111-MK 5-Hydroxymethylcytosine (5hmC) is the first oxidative product in the active demethylation of 5-methylcytosine (5mC). It not only marks active demethylation but also serves as a relatively stable DNA mark that plays distinct epigenetic roles. It is potentially important in epigenetics, because the hydroxymethyl group on the cytosine can possibly switch a gene on and off. 5hmC is abundantly expressed, but the levels vary significantly depending on the cell type. The highest levels are found in neuronal cells of the central nervous system.
