NP-1 Recombinant eiwit

Defensins (alpha and beta) are cationic peptides with a broad spectrum of antimicrobial activity that comprise an important arm of the innate immune system. The α -defensins which include NP-1, NP-2 and NP-3, are distinguished from the β -defensins by the pairing of their three disulfide bonds. In addition to antimicrobial activity, NP-1 exhibits chemotactic activity on dendritic cells. NP-1 is expressed as the C-terminal portion of an inactive precursor protein, which also contains a 19 amino acid N-terminal signal sequence and a 45 amino acid polypeptide. NP-1 contains a six-cysteine motif that forms three intra-molecular disulfide bonds. Recombinant human NP-1 is a 3.4 kDa protein containing 30 amino acid residues.

Room Temp

The lyophilized NP-1 recombinant protein is stable for at least 2 years from date of receipt at -20˚ C. Reconstituted NP-1 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚ C. As with any protein, exposing NP-1 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
