Source
PE-Labeled Human HLA-A*02:01&B2M&PRAME (ALYVDSLFFL) Tetramer Protein (HLE-HP2E3) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Ile 308 (HLA-A*02:01) & Ile 21 - Met 119 (B2M) & ALYVDSLFFL (Accession # AAA59606.1 (HLA-A*02:01) & P61769-1 (B2M) & ALYVDSLFFL).
Predicted N-terminus: Gly 25 & Ile 21
Request for sequenceMolecular Characterization
PE-Labeled Human HLA-A*02:01&B2M&PRAME (ALYVDSLFFL) Tetramer Protein is assembled by biotinylated monomer and PE-labeled streptavidin.
Biotinylated Human HLA-A*02:01&B2M&PRAME (ALYVDSLFFL) Complex Protein is produced by co-expression of HLA and B2M loaded with PRAME peptide. Biotinylated Human HLA-A*02:01&B2M&PRAME (ALYVDSLFFL) Complex Protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

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.
