The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 - 4 µg/ml.
Recommend PFA Fixation and Triton X-100 treatment
1/50 - 1/200. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
In the hair cortex, hair keratin intermediate filaments are embedded in an interfilamentous matrix, consisting of hair keratin-associated proteins (KRTAP), which are essential for the formation of a rigid and resistant hair shaft through their extensive disulfide bond cross-linking with abundant cysteine residues of hair keratins. The matrix proteins include the high-sulfur and high-glycine-tyrosine keratins.
Immunofluorescent staining of Human cell line A-431 shows positivity in nuclear membrane, plasma membrane and cell junctions. Recommended concentration of ab122172 1-4 µg/ml. Cells treated with PFA/Triton X-100.
