Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
-
Shipping
In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.

Protein Description
The HLA-A*02:01/B2M/p53(GLAPPQHLIRV) monomer is a significant focus in cancer immunology and vaccine development. HLA-A*02:01 is one of the most prevalent human leukocyte antigen (HLA) class I molecules, playing a critical role in presenting peptide antigens to CD8+ T cells, which are essential for eliciting an immune response against tumors. The p53 protein, a well-known tumor suppressor, is frequently mutated in various cancers, leading to altered peptide sequences, including the specific epitope GLAPPQHLIRV. The study of this monomer involves the recombinant expression of the HLA-A*02:01 complexed with β2-microglobulin (B2M) and the p53-derived peptide, enabling researchers to investigate its structure, binding affinity, and immunogenicity. Understanding the interactions between these components can provide insights into T cell receptor recognition and guide the design of targeted immunotherapies or vaccines aimed at eliciting effective antitumor responses. Moreover, this research may also contribute to the understanding of immune evasion mechanisms employed by tumors, further paving the way for innovative therapeutic strategies.
