This lyophilized preparation is stable for 12 months from date of receipt at -20 to -70 degrees C, preferably desiccated. Upon reconstitution, the preparation can be stored for 1 month at 2-8 degrees C under sterile conditions, and for 3 months at -20 degrees C to -70 degrees C. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Stock solutions should be aliquoted and stored at < -20 degrees C. Further dilutions should be made in appropriate buffered solutions

Purity

> 97 % pure by SDS-PAGE and HPLC

Endotoxin Level

Less than 0.1 EU/ug of Protein A as determined by LAL method.

Predicted Molecular Mass

33.4 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Activity

Protein A is a genetically engineered protein containing 5 IgG-binding regions of protein A. Cell wall binding region, cell membrane binding region and albumin binding region have been removed from the recombinant Protein A to ensure the maximum specific IgG binding. The recombinant Protein A is ideal for purification of polyclonal or monoclonal IgG antibodies. Protein A binds to various human, mouse and rat IgG subclasses. It also binds to total IgG from rabbit, guinea pig, pig, dog and cat.

Specificity

Protein A binds to various human, mouse and rat IgG subclasses (e.g., human IgG1, IgG2, IgG4; mouse IgG2a, IgG2b, IgG3; rat IgG2c). It also binds to total IgG from rabbit, guinea pig, pig, dog and cat.

Background: Protein A

Protein A is a cell wall component produced by several strains of Staphylococcus aureus that consists of a single polypeptide chain and contains little or no carbohydrate. Recombinant Protein A is produced in E.Coli and functions essentially the same as native Protein A. It consists of 5 IgG-binding domains E-D-A-B-C aligned in series.
