Frequently Asked Questions (FAQ)
Question:  I am interested in specifically immunostaining sAC in melanocytes

Answer:  sAC is a ubiquitously expressed protein and therefore is present in all cell types of the epidermis. However it is expressed at highest level in the melanocytes. Suggested dilution for antibody is optimized to immunostain ALL cells in a variety of tissue types and tissue specie. Therefore, most end users who are specifically interested in human skin melanocytes have needed to dilute the antibody far below our suggested levels to remove unneeded keratinocyte staining and highlight the melanocyte staining.
