Source
Biotinylated Cynomolgus / Rhesus macaque FcRn Heterodimer Protein, His,Avitag&Strep II Tag (FCM-C82W5) is expressed from human 293 cells (HEK293). It contains AA Ala 24 - Ser 297 (FCGRT) & Ile 21 - Met 119 (B2M) (Accession # Q8SPV9-1 (FCGRT) & Q8SPW0-1 (B2M)). In the region Ala 24 - Ser 297 (FCGRT) & Ile 21 - Met 119 (B2M), the amino acid sequences of Cynomolgus and Rhesus macaque FcRn (FCGRT & B2M) are identical.
Predicted N-terminus: Ala 24 (FCGRT) & Ile 21 (B2M)

Other Tags and Version Biotin & Other Labeled Version
Biotinylated Cynomolgus / Rhesus macaque FcRn Heterodimer Protein, His,Avitag&Strep II Tag, produced by co-expression of FCGRT and B2M, has a calculated MW of 34.1 kDa (FCGRT) and 13.0 kDa (B2M). Subunit FCGRT is fused with an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag and subunit Beta-2 microglobulin (B2M) is fused with a Strep II tag at the C-terminus. The reducing (R) protein migrates as 40 kDa (FCGRT) and 14 kDa (B2M) respectively due to glycosylation.

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.
