Background
Psoriasin/HID-5 was originally identified as an up-regulated protein in psoriatic keratinocytes (1). Subsequently, this protein was found to have elevated expression in abnormally differentiating primary keratinocytes and in various carcinomas, including ductal carcinoma in situ (2-3). Psoriasin/HID-5 may play a role in the establishment or maintenance of these pathologies, and may serve as a diagnostic marker of particular tumor types or abnormally proliferative epithelia.

Antigen
This antibody was developed against recombinant psoriasin/HID-5 protein.

Genebank Info (Protein)

15. Chemotactic activity of S100A7 (psoriasin) is mediated by the receptor for advanced glycation end products and potentiates inflammation with highly homologous but functionally distinct S100A15.

Notes:
1. The IMG-409 antibody is specific for S100A7, it recognized recombinant human S100A7 but not other closely related human S100 recombinant proteins. That is, the antibody does not recognize S100A8, S100A10 or S100A15 (Fig 1A).  
2. The IMG-409 antibody detects both the low and high molecular weight forms of S100A7 in human keratinocytes (Fig 1A).
