Recombinant Human HLA-DPA1 Protein，His

HLA-DPA1

The HLA-DPA1 protein is critical in the immune system, binding antigens in the endocytic pathway of APCs and presenting them to the cell surface for recognition by CD4 T cells. The peptide binding cleft can accommodate peptides of 10-30 residues, mainly resulting from protein degradation. HLA-DPA1 Protein, Human (His) is the recombinant human-derived HLA-DPA1 protein, expressed by E. coli , with N-His labeled tag.

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.

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.

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.
