General description

Native protein A from Staphylococcus aureus. Provides a versatile and economical means for isolating, detecting, and purifying antibodies. It is especially useful in immunohistochemical studies because, unlike secondary antibodies, it does not bind to cell Fc receptors and, therefore, will not give high background reactions. Strongly reactive with guinea pig; human IgG1, IgG2, and IgG4; mouse IgG2b, and rabbit. Weakly reactive with bovine; human IgA, IgE, and IgM; and mouse IgG3. Nonreactive with goat; horse; human IgD and IgG3; rat; mouse IgG1; and sheep.

Warning

Toxicity: Standard Handling (A)

Reconstitution

Following initial thaw, aliquot and freeze (-20°C). Stock solutions are stable for up to 3 months at -20°C.
