    E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

  • 产品描述：
    Recombinant Mouse Lymphotoxin-alpha (Lta) is a partial length protein expressed with an N-terminal His-tagged or Tag-Free. Its expression region corresponds to 34-202aa of mouse Lta protein. Its purity was determined by SDS-PAGE and reached up to 85%. This recombinant Lta protein may be used to synthesize antibodies against Lta or on the studies of Lta-associated signal transduction.
    Lta is a cytokine that in its homotrimeric form binds to TNFRSF1A/TNFR1, TNFRSF1B/TNFBR and TNFRSF14/HVEM. In its heterotrimeric form with LTB binds to TNFRSF3/LTBR. Lymphotoxin is produced by lymphocytes and cytotoxic for a wide range of tumor cells in vitro and in vivo. Accumulating evidences have showed that expression of LT alpha and beta on acinar cells in mice led to chronic pancreatitis and sufficed to reproduce key features of human autoimmune pancreatitis including the development of autoimmunity and AIP associated secondary extra pancreatic pathologies.

■ 常见问题解答
Q:

Please provide the following information regarding CSB-EP013218MO (all expression systems)
1) Can this product be administered to mice?
2) Would you be able to provide this product lyophilized? Based on question 1, do you not recommend lyophilizing this product as it may lower activity?
3) We would like to know the standard and low endotoxin level would be for this product.

A:
Very nice to receive your inquiry.
①In theory, it can be administered to mice, but we have not done relevant experiments, it is recommended to purchase a small size to have a try first.
②We can provide this protein in lyophilized form, Please use deionized sterile water to reconstitute protein after the customer receives it.
(Dissolve completely. The concentration could depend on customers' experiment demand.)
Yes, lyophilization may damage the structure of the protein and may affect the activity of the protein, probably it's better to order liquid form,
and if there is any requirement for glycerol content when you choose liquid form, please let us know in advance.
③ Customer would like to know the standard and low endotoxin level would be for this product.
We can provide the endotoxin removal service free of charge to ensure that the final/low endotoxin level will be less than 1.0 EU/ug. The endotoxin level will be shown in the COA report. Please request for COA of the previous Lot for your reference if you need.
