One of the best producers is strain Cowan I (ATCC-12598; NCTC-8530) which contains
about 1.7% protein A by weight and its cell wall contains 6.7% protein A. Protein A is mainly …

Protein A has been isolated from a methicillin‐resistant strain of Staphylococcus aureus,
A676, which produces only extracellular protein A. The material is homogeneous after a one …

Protein A from Staphylococcus aureus is covalently linked to the peptidoglycan part of the
cell wall [1, 21. It can be released from the cells by digestion with lysostaphin, and this …

To study the active site (s) in protein A, partial tryptic digestions of the protein and of intact
Staphylococcus aureus were performed. Fragments which bind to the Fc‐part of human IgG …

Protein A from Staphylococcus aureus was brought to common attention in 1958 by Jensen,
l? 2 who found that most S. aureus strains contained an extractable product which …

The use of protein A from S. aureus (SpA) as an anti-IgG reagent in immunological
techniques has extended in recent years, together with knowledge about its interaction with …

Previous methods which have been used for the preparation of protein A, such as thermal
release of protein A with lysozyme from the bacteria, have given a heterogenous product in …

Publisher Summary This chapter discusses the reactivity of 125 I-labeled protein A with IgG
and its use as a tracer in radioimmunoassay. Protein A (PA) is a cell wall component …

Staphylococcus aureus strains from human infections and from bovine cases of acute and of
chronic mastitis were studied regarding protein A content. Human strains as well as bovine …
