Use in combination with:

Detection Reagent: Human TSLP Biotinylated Antibody (Catalog # BAF1398)

Standard: Recombinant Human TSLP Protein (Catalog # 1398-TS)

Measured by its ability to neutralize TSLP-induced proliferation in the BaF3 mouse pro‑B cell line co-transfected with human IL‑7 R alpha and TSLP R. The Neutralization Dose (ND50) is typically 0.05-0.25 µg/mL in the presence of 0.5 ng/mL Recombinant Human TSLP.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Cell Proliferation Induced by TSLP and Neutralization by Human TSLP Antibody. Recombinant Human TSLP (Catalog # 1398-TS) stimulates proliferation in the BaF3 mouse pro-B cell line co-transfected with human IL-7 Ra and TSLP R in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human TSLP (0.5 ng/mL) is neutralized (green line) by increasing concentrations of Sheep Anti-Human TSLP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1398). The ND50 is typically 0.05-0.25 µg/mL.

Background: TSLP

Thymic Stromal Lymphopoietin (TSLP) was originally identified as an activity from the conditioned medium of a mouse thymic stromal cell line that promoted the development of B cells. The activities of mouse TSLP overlap with, but are distinct from, those of mouse IL-7. Both mouse TSLP and IL-7 can co-stimulate growth of thymocytes and mature T cells, and support B lymphopoiesis in long-term cultures of fetal liver cells and bone-marrow cells. Whereas mouse IL-7 facilitates the development of B220+/IgM- pre-B cells, mouse TSLP promotes the development B220+/IgM+ B cells. Human TSLP was reported to preferentially stimulate myeloid cells; inducing the release of T cell-attracting chemokines from monocytes and enhancing the maturation of CD11c+ dendritic cells. Human TSLP cDNA encodes a 159 amino acid (aa) residue precursor protein with a 28 aa signal sequence. Within the mature region, six of the seven cysteine residues present in the mouse TSLP involved in intramolecular disulfide bond formation are conserved in the human TSLP. Human TSLP shares approximately 43% aa sequence identity with mouse TSLP. By Northern blot analysis, human TSLP expression has been detected in many tissues with the highest expressions in heart, liver, testis, and prostate. TSLP signals through a heterodimeric receptor complex that consists of IL-7 R alpha and the TSLP R, a member of the hemopoietin receptor family most closely related to R gamma c.

Human TSLP Antibody
By Anonymous on 06/09/2020
Application: ELISA Sample Tested: Serum and Plasma Species: Human

We used this antibody in an in-house ELISA along with mAb (1398) and protein (1398-TS-010) to quantify TSLP in human serum and plasma. This combination could not detect TSLP samples but generated a good standard curve.

Application: ICC/IF Sample Tested: Adult lung Species: Human

Did not work with and without citrate retrieval. IgG used as control and a different protein marking the same cells was seen.
