Other Tags and Version Biotin & Other Labeled Version
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 80.9 kDa. The protein migrates as 95-100 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 0.01 EU per μg by the LAL method / rFC method.
Sterility
Negative
Purity
>95% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in 100 mM Glycine, 150 mM NaCl, 25 mM Arginine, 50 mM Tris, pH7.5 with trehalose as protectant.

いいねI have been using ACRO Biosystems products since 2021, especially DLL4 Fc proteins (DL4-H5259), refer to our published article: https://pubmed.ncbi.nlm.nih.gov/37795096/, where we have used Acro-products and obtained excellent results. I am very satisfied with the consistent quality and reliability of ACRO’s products. Thanks, Ankit Tanwar Staff Scientist AECOM, NY- Z***a2022-07-06 いいねThis product was extremely useful for our T cell work. The vial it came in was easy to use (sometimes you'd be surprised how obtuse the packaging of a compound can be by certain companies) and has not lead to any issues with our research in many months. The only obstacle we have ever faced with adherent cells was as a result of our flat bottom plates being too old (and thus the coating wore off). So this product was more stable and consistent than the plates we put them on!
