Nuclear Fast Red counterstain

Our Nuclear Fast Red is a light red nuclear counterstain designed for counterstaining immunohistochemistry chromogens like BCIP/NBT (Cat. No. GTX73326), BCIP/INT (Cat. GTX73325), DAB Cobalt (Cat. No. GTX73331). This is an ideal counterstain to be used with the chromogens that cannot be counterstained with hematoxylin because of the little or no color contrast. Specimens counterstained with Nuclear Fast Red can be dehydrated and mounted with organic solvents-based plastic polymers such as Clarion (Cat. No. GTX73339, GTX7334) or Permount. This light red nuclear counterstain is designed for counterstaining BCIP/NBT and DAB Cobalt. Specimens counterstained with Nuclear Fast Red should be dehydrated and mounted with an organic mounting media such as Clarion (See Pg. 54). This counterstain is not compatible with aqueous mounting media. Nuclear Fast Red Counterstain is not compatible with Crystal/Mount, Gel/Mount or other aqueous mounting media.
