Human beta Defensin-4 Recombinant

Defensins are a large family of peptides of which two groups exist in mammals: alpha defensins and beta defensins, which are distinguishable by the spacing and connectivity of the conserved cysteine residues within the mature peptides. It is thought that defensins function in the eradication of pathogens from the host system by inserting themselves into the bacterial membrane under the influence of membrane potential, forming channels which lead to leakage of cytoplasmic molecules and cell death.

Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.

The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.
