TSLP Protein, Human (Biotinylated, HEK293, His-Avi)

Customer Review

Based on 1 Customer Validation

TSLP Protein, a cytokine, stimulates T-cell-attracting chemokine release from monocytes and enhances CD11c(+) dendritic cell maturation. It directly activates mast cells, possibly inducing allergic inflammation. TSLP may also possess antimicrobial properties in the oral cavity and on the skin. TSLP Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived TSLP protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Biological Activity

Description

TSLP Protein, a cytokine, stimulates T-cell-attracting chemokine release from monocytes and enhances CD11c(+) dendritic cell maturation. It directly activates mast cells, possibly inducing allergic inflammation. TSLP may also possess antimicrobial properties in the oral cavity and on the skin. TSLP Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived TSLP protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Background

The TSLP protein is a cytokine that stimulates the release of T-cell-attracting chemokines from monocytes, with a particular effect on enhancing the maturation of CD11c(+) dendritic cells. Additionally, this protein can directly activate mast cells, potentially leading to the induction of allergic inflammation. It is also suggested that TSLP may have antimicrobial properties in the oral cavity and on the skin.
