Recombinant Human CD55/DAF Protein(HEK293), hFc

CD55/DAF

The CD55/DAF protein is critical in the immune system, recognizing C4b and C3b fragments, interfering with their enzymatic conversion and preventing the formation of complement cascade amplifying convertase. This regulatory mechanism alleviates complement-induced damage by inhibiting complement activation. CD55/DAF Protein, Human (HEK293, hFc) is the recombinant human-derived CD55/DAF 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.
