CYTOKERATIN ANTIBODIES
(anti-Human and others as indicated)
RDI Division of Fitzgerald Industries Intl offers a wide line of antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.
