Detection of Sos-1 by immunoblotting is possible by using a minimum antibody working dilution of 1:4,000 in whole extracts of A431 (human epidermoid carcinoma) and PC 12 (rat pheochromocytoma) cell lines. For indirect immunofluorescent staining a minimum working dilution of 1:500 may be used in cultured canine MDCK cells. The antibody is suitable for protein microarray.
