DBP

DBP (β-defensin) is a recombinant protein composed of 30-40 amino acid residues, featuring a stable disulfide bond structure that endows it with high stability and biological activity. As an essential component of the innate immune system, DBP possesses extensive antibacterial, antiviral, antifungal, and antitumor functions. It inhibits the growth and reproduction of microorganisms by recognizing and binding to specific receptors on their surfaces, thereby disrupting their cell membranes. Additionally, DBP can activate the immune response of host cells, promoting the release of inflammatory mediators and further enhancing the body's defense capabilities. These biological effects make DBP indispensable in maintaining the health of the organism and resisting the invasion of external pathogens.

Validated Data

(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.

Based on the SEQUEST from database of Yeast host and target protein, the LC-MS/MS Analysis result of CSB-YP009306HU could indicate that this peptide derived from Yeast-expressed Homo sapiens (Human) GC.

The following DBP reagents supplied by CUSABIO are manufactured under a strict quality control system. Multiple applications have been validated and solid technical support is offered.
