Human Plasma Alpha 2-macroglobulin
Activation of plasma kallikrein arginine esterase activity by kaolin resulted in peak activity at 1 min of incubation and a 50% reduction in activity at 5 min in normal plasma, and 30% reduction in the plasma of patients with hereditary angioneurotic edema who lacked the C1 inactivator. The peak esterolytic activity was inhibited by soybean trypsin inhibitor whereas the 5 min activity was resis...
متن کاملSpecific covalent binding of platelet-derived growth factor to human plasma alpha 2-macroglobulin.
Attempts to measure the platelet-derived growth factor (PDGF) in human plasma resulted in the discovery of a specific plasma binding protein. The 125I-labeled PDGF (125I-PDGF)-plasma binding protein complex retained mitogenic activity but lost reactivity against rabbit anti-PDGF antiserum. Copurification of the plasma binding protein and alpha 2-macroglobulin (alpha 2M) in human plasma, the for...
متن کاملIsolation and molecular characterization of a novel albumin-binding protein from group G streptococci.
Many streptococcal strains are known to bind the two most abundant plasma proteins, namely, immunoglobulin G and albumin. Protein G isolated from group C and G streptococci has been demonstrated to have separate binding regions for each of these proteins. However, some group G streptococcal strains bind only serum albumin. This report describes the isolation of a 48-kDa albumin-binding protein ...
متن کاملA NEW CHARACTERIZATION OF SIMPLE GROUP G 2 (q) WHERE q ⩽ 11
Let G be a finite group , in this paper using the order and largest element order of G we show that every finite group with the same order and largest element order as G 2 (q), where q 11 is necessarily isomorphic to the group G 2 (q)
متن کاملHigh Serum Alpha-2-Macroglobulin Level in Patients with Osteonecrosis of the Femoral Head
Background: Diagnosis of osteonecrosis of the femoral head (ONFH) is complicated due to the lack of reliable serum biomarkers. Up-regulation of alpha-2-macroglobulin (A2M) gene has been reported in glucocorticoid-induced ANFH rat model. This study aimed to investigate whether the serum level of alpha-2-macroglobulin (A2M) can be used for ONFH diagnosis. Methods: Serum protein capillary elect...
