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 SABA assay / 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.

LikesThis 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.- M***h2022-04-01 LikesThis 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.
FAQ
- product
Can lyophilized proteins remain stable during room-temperature shipping or temporary room-temperature exposure?
In general, lyophilized proteins remain stable during room-temperature shipping or temporary exposure to room-temperature conditions.
Many ACROBiosystems recombinant proteins are supplied in lyophilized (freeze-dried) form. The lyophilization process effectively removes moisture from the product, helping reduce degradation-related reactions and improve protein stability during transportation and storage.
To evaluate the stability of lyophilized proteins under normal temperature conditions, ACROBiosystems conducted a stability study on 11 representative lyophilized protein products at 37°C. The study demonstrated that these proteins maintained good quality stability after storage at 37°C for approximately 20 days. Based on these validation results, temporary room-temperature exposure during shipping or handling is generally not expected to have a significant impact on product quality or downstream application performance.
To ensure optimal long-term stability, products should be stored according to the storage conditions specified in the product Certificate of Analysis (COA) upon receipt.
