The Small Subunit of Hl-a Antigens Is Β2-microglobulin
ItL-A antigens prepared from human lymphoid cells by treatment of either intact cells or membranes with papain or nonionic detergents have been shown to contain two polypeptide chains. The antigen prepared by treatment of cells or cell membranes with papain contains polypeptide chains with a mol wt of about 34,000 and 11,000 (1), whereas the detergent-solubilized antigen has polypeptides of too...
متن کاملHuman tumour-associated and tumour-specific antigens: some concepts in relation to clinical oncology.
The concept of tumour-specific antigens is constantly undergoing reappraisal with the development of more sensitive methods for their detection. This has resulted in the finding that the many 'new' antigens produced by human tumours or materials immunologically closely related to them are also present in non-neoplastic tissues, albeit in small amounts. However, other antigens still appear to ex...
متن کاملNovel Antibacterial Activity of β2-Microglobulin in Human Amniotic Fluid
An antibacterial protein (about 12 kDa) was isolated from human amniotic fluid through dialysis, ultrafiltration and C18 reversed-phase HPLC steps. Automated Edman degradation showed that the N-terminal sequence of the antibacterial protein was NH(2)-Ile-Gln-Arg-Thr-Pro-Lys-Ile-Gln-Val-Tyr-Ser-Arg-His-Pro-Ala-Glu-Asn-Gly-. The N-terminal sequence of the antibacterial protein was found to be ide...
متن کاملAmniotic Fluid β2- Microglobulin Measurements
OBJECTIVE: To determine β2-microglobulin levels in amniotic fluid during the course of second trimester. STUDY DESIGN: One hundred patient’s amniotic fluid β2-microglobulin levels had been evaluated retrospectively (March-October 2009). The most common amniocentesis indication was advanced maternal age (33.3%). Others were; high risk result for triple test (18.5%), high risk result for double t...
متن کاملRelationship between Hl-a Antigens and Β2-microglobulin as Studied by Immunofluorescence on the Lymphocyte Membrane
The antibody-induced redistribution of beta2-microglobulin (beta2-micro) and HL-A antigens on the surface of living lymphocytes was studied by immunofluorescence. When all beta2-micro was redistributed on the lymphocyte membrane by specific rabbit antibodies and goat antirabbit Ig conjugates, the HL-A antigens were no more detectable with anti-HL-A conjugates outside the beta2-micro caps alread...
