Endotoxin Level

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

Predicted Molecular Mass

46.7 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. 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 (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.

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.

Alternate Names

PROA, Protein-A

FAQs for Recombinant Protein A Long Form Protein

Showing  1 - 1 of 1 FAQ Showing All
  • Q: During my master thesis, I am working on a large scale ribosome affinity purification in Trypanosoma brucei. Unfortunately, we have some problems with the present antibody (IgG against protein A, extracted from chicken). Therefore, we are searching a better and more efficient alternative. Ideally it is extracted from guinea pig, rat, mouse or rabbit. Searching suitable antibodies, I found you have some in your range of products. Since we need to work large scale and will need a bigger amount of antibodies the next months, we would like to get the possibility to test the new antibodies first. Therefore I would like to ask for an aliquot for testing. You would really help me finding an good alternative!

    A:

    We unfortunately cannot offer testing samples of our antibodies. I am sorry for any inconvenience. We do have two antibodies to Protein A that meet your host requirements. We fully guarantee our antibodies for all listed species and applications. For any applications and/or species not listed, we offer our Innovators Reward Program. In exchange for a review of your experiment using our product in an untested application or species, we will issue you a credit for the purchase price of the antibody.
