CD22 Antibody (BL-CAM; clone FPC1)

Mouse monoclonal antibody suitable for immunohistochemistry.



Functional Aspects:

CD22 is present both on the membrane and in the cytoplasm of B lymphocytes. Surface expression, however, is variable and may be lost upon differentiation. CD22 has been reported to be present in certain leukemias. It is absent from peripheral blood T cells, T cell leukemias, granulocytes, and monocytes. Clone FPC1 was raised against the external domain of CD22.
