ICC/IF Use at an assay dependent concentration. PubMed: 23627872


  • 功能
    Exhibits antimicrobial activity against Gram-positive bacteria S.aureus and S.pyogenes, Gram-negative bacteria P.aeruginosa and E.coli and the yeast C.albicans. Kills multiresistant S.aureus and vancomycin-resistent E.faecium. No significant hemolytic activity was observed.
  • 组织特异性
    Highly expressed in skin and tonsils, and to a lesser extent in trachea, uterus, kidney, thymus, adenoid, pharynx and tongue. Low expression in salivary gland, bone marrow, colon, stomach, polyp and larynx. No expression in small intestine.
  • 序列相似性
    Belongs to the beta-defensin family.

  • ab19270 staining beta Defensin 3 in the A549 cell line from Human Lung by ICC/IF (Immunocytochemistry/immunofluorescence) treated with cigarette smoke extract. Cells were fixed , permeabilized and blocked. Samples were incubated with primary antibody (1/500) for 1 hour. An  Alexa Fluor®488-conjugated  was used as the secondary antibody and DAPI used to stain the nuclei.

Does your customer want to use the same catalog numbers or would she be interested in choosing one or more different antibodies (of the same price) to the beta defensin proteins?

Thanks for passing along the peptide and protein concentration information.

These concentrations seem reasonable.

Is your customer interested in replacements for the antibodies?

Thank you for sending along the dot blots and additional information. We really appreciate the extra troubleshootingeffort.

Here are my thoughts:

1. In general it looks like the antibodies are able to detect Defensin in the chorioam...
