Synonyms
N/A
Purity
>96% by SDS-PAGE and RP-HPLC analyses.
Biological Activity
The recombinant Protein A/G is a genetically engineered protein containing 5 IgG-binding regions of protein A and 3 of protein G. Cell wall binding region, cell membrane binding region and albumin binding region have been removed from the recombinant Protein A/G to ensure the maximum specific IgG binding. The recombinant Protein A/G is ideal for purification of polyclonal or monoclonal IgG antibodies. Protein A/G binds to various human, mouse and rat IgG subclasses (e.g., human IgG1, IgG2, IgG3, IgG4; mouse IgG2a, IgG2b, IgG3; rat IgG2a, IgG2c). It also binds to total IgG from cow, goat, sheep, house, rabbit, guinea pig, pig, dog and cat.
Physical Appearance

Formulation
Lyophilized from additive free solution.
Endotoxin
Less than 0.1EU/μg of Protein A/G, His-tag as determined by LAL method.
Reconstitution
Dissolve in distilled water or saline.
Category
Protein A/G
Background
The recombinant Protein A/G consists of 8 IgG-binding domains EDABC-C1C2C3, which corresponds to the Protein A and G domains that are included in the recombinant sequence. The Protein A portion is from Staphylococcus aureus segments E, D, A, B and C. The Protein G portion is from Streptococcus segments C1, C2 and C3. The binding capacity of recombinant Protein A/G is broader than either Protein A or Protein G alone.
