Protein G

• Catalog Number: orb82629
• Category: Proteins
• Description: The recombinant Protein G, containing 196 amino acid residues which is amino acid 190-384 of the Streptococcus sp, has a predicted molecular mass of approximately 21.6 kDa. But it migrates with an apparent molecular mass of 32kDa in SDS-PAGE.
• Target: Protein G. 1. Binds with greater affinity to most mammalian immunoglobulins than Protein A, including human IgG3 and rat IgG2a.
  2. Does not bind to human IgM, IgD and IgA.
• Conjugation: Unconjugated
• Buffer/Preservatives: Lyophilized with no additive. Dissolve in distilled water or saline.
• Purity: > 95% pure by SDS-PAGE analyses.
• Tested applications: FA, HPLC, SDS-PAGE
• Biological Origin: E.coli
• Biological Activity: Less than 0.1 EU/μg of Protein G as determined by LAL method.
• Storage: Store at 4°C for up to two weeks. For long term storage, aliquot and store at -20°C, avoid freeze/thaw cycles.
