Chemiluminescence immunoassay for somatomedin C in serum.
To select the best tracer for use in a competitive immunoassay, we conjugated human somatomedin C (SmC) to various chemiluminescent compounds via two different synthetic pathways. Naphthylhydrazides and arylhydrazides, used as the labels, were incorporated via their imidate or their succinimide esters. Conjugating the carboxy terminal of (amino ethyl)ethyl-isoluminol to SmC via a succinimide li...
متن کاملSomatomedin C deficiency in Asian sisters.
Two sisters of Asian origin showed typical clinical and biochemical features of primary somatomedin C (SM-C) deficiency (Laron dwarfism). Abnormalities of SM-C binding proteins were observed, one sister lacking the high molecular weight (150 Kd) protein.
متن کاملThe role of calcium in lymphocyte proliferation. (An interpretive review).
A small quantity of extracellular calcium is required for the stimulation of lymphocytes by mitogens such as plant lectins. Lectin binding to the lymphocyte surface and early postbinding events that eventually lead to DNA synthesis are calcium dependent. Mitogenic lectins such as PHA and Con-A rapidly increase the size of an exchangeable pool of cell calcium and cause a smaller rise in intracel...
متن کاملHepatitis C virus-associated B-cell proliferation--the role of serum B lymphocyte stimulator (BLyS/BAFF).
OBJECTIVE B lymphocyte stimulator (BLyS) is known to support B-cell proliferation (BCP) in B-cell haemopathies and autoimmune diseases. We assume that BLyS may play a role in the initiation and expression of hepatitis C virus (HCV)-associated BCP. We assessed BLyS serum levels in HCV-infected patients and in various forms of HCV-associated BCP [i.e. mixed cryoglobulin (MC), rheumatoid factor (R...
متن کاملAssay of somatomedin C by cartridge extraction prior to radioimmunoassay with antiserum developed against synthetic somatomedin C.
The whole molecule of human somatomedin C (SM-C) prepared by the total synthesis method was used as an antigen to produce an antiserum for a radioimmunoassay. Since plasma proteins that bind SM-C interfere with the assay, a method was developed that uses acid dissociation followed by C-2 cartridge extraction to strip SM-C from its binding proteins before assay. This assay has no cross-reactivit...
