For more information, read more on recombinant antibodies.
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.
Psoriasin also known as S100A7 is a member of the S100 protein family. It has a molecular mass of approximately 11.4 kDa. This protein exhibits calcium binding properties that influence its function. Psoriasin primarily expresses in keratinocytes which are predominant in the epidermis of the skin. Additionally it appears in various epithelia like mucous membranes. The expression levels rise in certain skin conditions suggesting it has a role in skin physiology.
Psoriasin acts as an antimicrobial peptide contributing to the skin’s defense system against microbial invasion. It helps in controlling the growth of bacteria like E. coli and fungi. The protein does not function as part of a larger complex. Instead it operates independently to maintain the integrity of the skin barrier. Psoriasin also shows involvement in the inflammatory response of the skin where it interact with other immune system players.
Several biological systems involve psoriasin including inflammation and skin homeostasis pathways. It interacts closely with other S100 proteins such as S100A8 and S100A9 which are part of the inflammatory process. These interactions can regulate immune cell migration and cytokine production highlighting its active role in modulating skin immune responses. Psoriasin serves as an important component in maintaining the balance between immune protection and inflammation within these pathways.
Psoriasin associates with psoriasis and breast cancer. In psoriasis it significantly increases aligning with its role in inflammation and skin barrier maintenance. The upregulation of psoriasin in psoriasis has been linked to overexpression of related proteins like S100A8 contributing to the chronic inflammatory state. In breast cancer particularly in certain carcinoma contexts its presence suggests a role in cancer cell survival. Researchers study its interaction with proteins in the cancer microenvironment to better understand its influence on tumor progression.
