Histostain®-SP (Streptavidin-Peroxidase) and Histostain®-SAP (Streptavidin-Alkaline Phosphatase) immunohistochemical staining kits employ the LAB-SA (Labeled [strept]Avidin-Biotin) method. For Histostain®-SP Kits, DAB or AEC chromogen/substrate generates a colored precipitate around the target antigen in human samples. DAB (brown) is approximately twice as sensitive as AEC (reddish). For Histostain®-SAP Kits, AP-Red or BCIP/NBT chromogen/substrate generates a colored precipitate around the target antigen in human samples. BCIP/NBT (dark blue/purple) is about twice as sensitive as AP-Red (red/magenta).
All components are liquid and come in easy-to-use, color-coded dropper bottles. Most reagents are supplied in prediluted form at working strength; substrate reagents require a simple dilution. No ABC complex formation, no reconstitution, and no pipetting are required. Ask us about using these kits with nonhuman samples.
