Recombinant Rat CTLA-4 Protein(HEK293), hFc

CTLA-4

CTLA-4 protein inhibits T-cell responses by binding strongly to CD80 and CD86 receptors, surpassing CD28. This affinity allows CTLA-4 to effectively regulate T-cell activation and immune responses. The balance between inhibitory and stimulatory signals controlled by CTLA-4 and its ligands modulates T-cell-mediated immune reactions. CTLA-4 Protein, Rat (HEK293, Fc) is the recombinant rat-derived CTLA-4 protein, expressed by HEK293 , with C-hFc 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.
