Protein per Gram Powder See Label.
Concentration for 1 unity DO at 280 nm 4.652 mg/ml
Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.
Purity > 97 % by SDS-PAGE and HPLC analyses.
Specificity The recombinant 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 (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.
Endotoxin Level Less than 0.1 EU/μg of Protein A, His as determined by LAL method.
Formulation Lyophilized from additive free solution.
Stability & Storage Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
- 12 months from date of receipt, -20 to -70 °C as supplied.

Reconstitution Dissolve in distilled water or saline.
Shipping The product is shipped at ambient temperature. Upon receipt, store it immediately at -20 °C.
SDS-PAGE
BackgroundProtein 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.
