Can Leucoperm™ (BUF09) be used for staining intracellular markers by indirect flow cytometry?
Yes, but AbD Serotec always advises the use of a direct conjugate where available. The use of a secondary antibody may result in a higher level of background staining. If intracellular staining is preceded by the staining of a cell surface antigen then particular care must be taken when selecting a secondary antibody.
