Other Tags and Version Biotin & Other Labeled Version
This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 75.6 kDa. The protein migrates as 100-116 kDa under reducing (R) condition, and 150 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
Labeling
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
Protein Ratio
Passed as determined by the HABA assay / binding ELISA.
Purity
>95% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

This protein product from Acrobio Systems is high-quality and easy to use. The biotinylation via Avitag™ ensures consistent labeling, and the Fc tag provides good stability. It worked well in our binding assays, delivering reliable and reproducible results. Great option for researchers studying immune checkpoints or receptor-ligand interactions. Additionally, the protein was delivered quickly and arrived in excellent condition, with clear documentation and high purity confirmed by SDS-PAGE. It demonstrated strong and specific binding in flow cytometry and ELISA setups. The consistent performance across experiments made it a dependable tool in our studies. Highly recommended for immunology and cell biology applications where ligand-receptor interactions are key.

This sample was highly pure which was very helpful in selection campaigns to find specific molecules. We did our own QC on the sample to verify purity and it matched up perfectly with SDS-PAGE and SEC-MALS that is provided on the website. Shipping was quick to prevent delays in our project timelines. This sample was sent lyophilized and very easy to reconstitute for use.
