Other Tags and Version Biotin & Other Labeled Version
Biotinylated Human ITGA2&ITGB1 Heterodimer Protein, His,Avitag&Tag Free, produced by co-expression of ITGA2 and ITGB1, has a calculated MW of 130 kDa (ITGA2) (E534K) & 83.7 kDa (ITGB1) (E534K). Subunit ITGA2 is fused with an acidic tail at the C-terminus and followed by a polyhistidine tag and an Avi tag (Avitag™) and subunit ITGB1 contains no tag but a basic tail at the C-terminus. The protein migrates as 150-180 kDa (ITGA2) (E534K) and 105-130 kDa (ITGB1) (E534K) when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) 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.
