Q:

I am interested in buying a ELISA Kit for Human Dermcidin (DCD) but I need to detect this protein in Saliva Samples.,
Do you have any information about if the kit that you offer have been ever tested with saliva samples?

A:
Thanks for your inquiry.
We use this kit to detect human saliva sample with 1:10 dilution and get the value is 2.5--10ng/ml, then the final concentration is 25--100ng/ml.Pls let me know if you have any further questions. Thank you.

  • 功能：
    DCD-1 displays antimicrobial activity thereby limiting skin infection by potential pathogens in the first few hours after bacterial colonization. Highly effective against E.coli, E.faecalis, S.aureus and C.albicans. Optimal pH and salt concentration resemble the conditions in sweat. Also exhibits proteolytic activity, cleaving on the C-terminal side of Arg and, to a lesser extent, Lys residues.; Survival-promoting peptide promotes survival of neurons and displays phosphatase activity. It may bind IgG.
