| Specificity: |
This kit recognizes Human DEF Beta 2/DEFB2 in samples. No significant cross-reactivity or interference between Human DEF Beta 2/DEFB2 and analogues was observed. |
| Sample Type: |
Serum, plasma and other biological fluids |
| Function | Exhibits antimicrobial activity against Gram-negative bacteria and Gram-positive bacteria, with highest activity against Gram-negative bacteria. Antimicrobial activity against P.aruginosa seems to be salt-sensitive and is reduced with high salt concentrations greater than 25 mM. Also exhibits antimicrobial activity against the yeast C.albicans. Permeabilizes C.albicans cell membranes via targeting plasma membrane lipid phosphatidylinositol 4,5-bisphosphate (PIP2), thereby leading to cell fragmentation and cell death. Acts as a ligand for C-C chemokine receptor CCR6. Binds to CCR6 and induces chemotactic activity of CCR6-expressing cells, such as immature dendritic cells and memory T cells. |
