Validation:

Recombinant Protein Validation (Figure 1) : Anit-TSLP antibodies (4021) detected human TSLP recombinant protein at different concentrations.

Regulated Expression Validation (Figure 4-8) : Anit-TSLP antibodies (4021) detected increased expression in multiple tissue or cells after treatment with cytokines or chemicals, in which the increase in the expression was inhibited by co-treatment with anti-cholinergic drugs (Figure 5) .

Isoform: Human TSLP has 2 isoforms, including isoform 1 (159aa, 18kD) and isoform 2 (63aa, 7kD) . Mouse TSLP has one isoform (140aa, 16kD) and rat TSLP also has one isoform (135aa, 16kD) . 4021 can detect only human isoforms, but cannot detect mouse and rat TSLP.

Alternate Name: TSLP Antibody: Thymic stromal lymphopoietin

User Note: Optimal dilutions for each application to be determined by the researcher.

BACKGROUND: TSLP Antibody: Thymic stromal lymphopoietin (TSLP) has recently been identified as an important factor capable of driving dendritic cell maturation and activation. TSLP is a four-helix-bundle cytokine that is expressed mainly by barrier epithelial cells and is a potent activator of several cell types such as myeloid dendritic cells. TSLP is involved in the positive selection of regulatory T cells, maintenance of peripheral CD4+ T cell homeostasis and the induction of CD4+ T cell-mediated allergic reaction. TSLP is also capable of supporting the growth of fetal liver and adult B cell progenitors and their differentiation to the IgM-positive stage of B cell development. Amino acid sequence analysis has shown poor homology between human and mouse TSLP although they exhibit similar biological functions and are expressed in similar tissues. At least two differentially spliced isoforms of TSLP are known to exist.
