TrkB (pS478) Positive Control Cell Lysate (Mouse NSC-34)-50 µg Reference: CL-2107-50 This cell lysate is suitable as positive control for Western Blotting, to confirm TrkB phosphorylation at amino acid S478 (rat/mouse) or S479 (human), respectively, using TrkB (pS478/479) rabbit antibody R-1718-50. It is particular useful for complex Western Blotting samples to identify TrkB (pS478/479) immunoreactive bands. This lysate has been prepared by triggering TrkB phosphorylation in retinoic acid-treated mouse NSC34 cells with mature BDNF, and subsequent processing with RIPA buffer. The cell lysate is provided lyophilised for extended stability.
Nitric Oxide Synthase Assay Kit Reference: ARG81188 Nitric oxide is a reactive free radical which acts as a biologic mediator in several processes, including neurotransmission and antimicrobial and antitumoral activities. Nitric oxide is synthesized from L-arginine by nitric oxide synthases. Variations in this gene are associated with susceptibility to coronary spasm. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009]
Alkaline Phosphatase Activity Assay Kit (Colorimetric) Reference: ARG81239 There are at least four distinct but related alkaline phosphatases: intestinal, placental, placental-like, and liver/bone/kidney (tissue non-specific). The first three are located together on chromosome 2, while the tissue non-specific form is located on chromosome 1. The product of this gene is a membrane bound glycosylated enzyme that is not expressed in any particular tissue and is, therefore, referred to as the tissue-nonspecific form of the enzyme. The exact physiological function of the alkaline phosphatases is not known. A proposed function of this form of the enzyme is matrix mineralization; however, mice that lack a functional form of this enzyme show normal skeletal development. This enzyme has been linked directly to hypophosphatasia, a disorder that is characterized by hypercalcemia and includes skeletal defects. The character of this disorder can vary, however, depending on the specific mutation since this determines age of onset and severity of symptoms. Alternatively spliced transcript variants have been described. [provided by RefSeq, Apr 2010]

AST / Aspartate Transaminase Assay Kit Reference: ARG81297 Glutamic-oxaloacetic transaminase is a pyridoxal phosphate-dependent enzyme which exists in cytoplasmic and mitochondrial forms, GOT1 and GOT2, respectively. GOT plays a role in amino acid metabolism and the urea and tricarboxylic acid cycles. The two enzymes are homodimeric and show close homology. [provided by RefSeq, Jul 2008]
ALT / Alanine Transaminase Assay Kit Reference: ARG81298 This gene encodes cytosolic alanine aminotransaminase 1 (ALT1); also known as glutamate-pyruvate transaminase 1. This enzyme catalyzes the reversible transamination between alanine and 2-oxoglutarate to generate pyruvate and glutamate and, therefore, plays a key role in the intermediary metabolism of glucose and amino acids. Serum activity levels of this enzyme are routinely used as a biomarker of liver injury caused by drug toxicity, infection, alcohol, and steatosis. A related gene on chromosome 16 encodes a putative mitochondrial alanine aminotransaminase.[provided by RefSeq, Nov 2009]
Cell Cycle / Apoptosis Analysis Kit Reference: ARG81299 The content of DNA is changed with the process of cell cycle. And the DNA can be stained by fluorescent dye to measure its intensity by flow cytometry to monitor the cell cycle distribution in G1, S, GS/M phase and as well as apoptosis and aneuploidy cells with signals at sub-G1 or super G2 region. Propidium iodide (or PI) is a fluorescent intercalating agent and it binds to DNA by intercalating between the bases with little or no sequence preference. Therefore PI is used widely as a DNA dye in flow cytometry to evaluate cell viability or DNA content in cell cycle analysis, or in microscopy to visualize the nucleus and other DNA-containing organelles. However, PI also binds to RNA, and it interference the DNA measurement in assay. In this Cell Cycle / Apoptosis Analysis Kit we provide a RNase to degrade RNA before PI staining to eliminate the interference by RNA and the kit can be used to monitor cell cycle progression, proliferation and apoptosis by flow cytometry.
