Detection of a New Antigen Associated With Chicken Thrombocytes on Marek's Disease Lymphoblastoid Cell Line

J Natl Cancer Inst. 1986 Jun;76(6):1085-94.

Abstract

A monoclonal antibody, 2C12, produced against MDCC-MSB1 cells, reacted with several cell lines derived from Marek's disease (MD), including MDCC-MSB1 cells, normal chicken thrombocytes, and MD tumor cells. It did not react with cell lines derived from avian leukosis or reticuloendotheliosis, cells from normal chicken thymus and bursa, chicken kidney cells and quail fibroblast cultures inoculated with MD virus, or with erythrocytes from 1-day-old and adult chickens, cow, sheep, and horse. Anti-thrombocyte serum prepared in a rabbit reacted with thrombocytes and MDCC-MSB1 cells. The specificities of antibody 2C12 and anti-thrombocyte serum against MDCC-MSB1 cells and thrombocytes were confirmed by cross-absorption, blocking, and double-membrane fluorescent antibody tests. The existence of a polypeptide with an apparent molecular weight of 103,000, common to both MDCC-MSB1 cells and thrombocytes, was demonstrated by Western blotting analyses.
