Comparison of albumin receptors expressed on bovine and human group G streptococci.
The albumin receptor expressed by bovine group G streptococci was extracted and affinity purified. The protein was characterized for species reactivity, and monospecific antibodies were prepared to the purified receptor. The bovine group G albumin receptor was compared functionally, antigenically, and for DNA homology with the albumin-binding protein expressed by human group G streptococci. In ...
متن کاملSpecific absorption of human serum albumin, immunoglobulin A, and immunoglobulin G with selected strains of group A and G streptococci.
Five gram-positive bacterial strains were selected for absorption studies of human serum samples. Strain AR1 (group A, M-type 1) and G148 (group G), with strong immunoglobulin G (IgG) binding capacities, and strain AW43 (group A, M-type 60), binding both IgA1 and IgA2, were compared with Staphylococcus aureus Cowan I and with Staphylococcus epidermidis L603. Both AR1 and G148 were capable of co...
متن کاملInteraction of Phthalocyanine with Egg albumin and Bovine serum albumin
The interaction of bovine serum albumin ( BSA) and egg albumin with water solublephthalocyanine, cobalt (ΙΙ) 4, 4′ , 4′′, 4′′′- tetrasulfophthalocyanine ( CoTSPc) , has been studiedby the UV- Vis method at pH 7.0 and five different temperatures 20, 25, 30, 35 and 40°C. Theformation constants have been elucidated by using spectrophotometric titration and computerSQUAD program data refinement. Th...
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 کاملSpecificities of albumin receptors and albumin antibodies.
Receptor sites for polymerized human serum albumin (pHSA) on the envelope of hepatitis B virus (hepatitis B surface antigen) and antibodies to pHSA in sera of patients with liver disease were differentiated by an indirect fluorescent antibody method. Analysis of the specificities of pHSA receptors and antibodies to pHSA by hemagglutination inhibition suggested that pHSA receptors reacted with a...
