نویسندگان
چکیده
SUMMARY Distribution among peripheral T lymphocyte subpopulations and biochemical properties of the chicken lymphocyte surface antigens defined by monoclonal antibodies (mAbs) Lc-4 and Lc-6 were examined. Two-color immunofluorescence analysis revealed that Lc-4 and Lc-6 antigens were expressed on mutually exclusive subpopula-tions of peripheral T lymphocytes but not on B lymphocytes. Lc-4 mAb precipitated a polypeptide with apparent molecular mass of 35 and 65 kilo dalton under reducing and non-reducing conditions, respectively. These results indicated that the antigen recognized with Lc-4 was closely similar in tissue distribution and biochemical property to mammalian CDS antigen.

متن کاملProduction and Characterization of Murine Monoclonal Antibodies to Leishmania Gp63 Antigen
Background : Production of monoclonal antibodies to Leishmania antigens assists the identification and characterization of these organisms. Objective: Production of monoclonal antibodies against epitopes on the gp63. Methods: Two murine monoclonal antibodies to gp63 were produced and characterized. The reactions of both antibodies with soluble leishmanial antigens, purified gp63 and truncated r...
متن کاملProduction and Characterization of Monoclonal Antibodies Recognizing a Common 57-kDa Antigen of Leishmania Species
Background: The therapy of leishmania infection is difficult and each year 1.5 million new cases of cutaneous leishmaniasis and 500,000 new cases of visceral leishmaniasis are estimated, therefore, there is a need for an effective vaccine. Monoclonal antibody (mAb) is one of the suitable methods for isolation and purification of leishmania antigens. In this report, we produced several mAb aga...
متن کاملIdentification of Two Epitopes on the Outer Surface Protein A of the Lyme Disease Spirochete Borrelia burgdorferi
A murine IgM monoclonal antibody (MA-2C6) with κ-light chains directed against an antigenic determinant of outer surface protein A (OspA) of the Lyme disease spirochete, Borreliaburgdorferi, is produced. This antibody could bind specifically to OspA antigen of several isolates of B. burgdorferi, but not to the non-Lyme disease bacteria such as T. pallidum and B. hermsii. Antibody MA-2C6 was pur...
متن کاملProduction, Purification and Characterization of Chicken Egg Yolk Monoclonal Antibody Against Colonization factor antigen -1 of Enterotoxigenic Escherichia coli Causing Diarrhea
Enterotoxigenic Escherichia coli (ETEC) causes diarrhea in both humans and animals. The contaminated food and water are the most common vehicles for ETEC infection. The colonization factor antigen (CFA-1) is a fimbriae protein that promotes adherence of the ETEC strain to the epithelium of the small intestine of the host. In this study IgY proteins were produced against the CFA-1 of ETEC in imm...
