Proteins

Protein A

Protein A is a 42 kDa surface protein originally found in the cell wall of the bacteria Staphylococcus aureus. Protein A binds strongly to the Fc region of IgG from human (total IgG, IgG1, IgG2 and IgG4), mouse (IgG2a, IgG2b and IgG3), rabbit, guinea pig, pig, dog, and rhesus monkey.
For convenient amino-based conjugation, the product is free from amino-based puffers. Protein A is useful as reagent for coating or detecting specified IgG in ELISA and immunoblotting procedures.

Streptavidin

Streptavidin binds to biotin with high affinity. The streptavidin-biotin bond is one of the strongest non-covalent interaction in nature, making it extraordinarily robust. For convenient amino-based conjugation, the product is free from amino-based puffers. Streptavidin is useful as reagent for coating or detecting biotinylated molecules in ELISA and immunoblotting procedures.
