TSLP recombinant protein

TSLP

Cat. Num. AAA517735

• Applications: Cell Assay
• Synonyms: TSLP; Thymic stromal lymphopoietin; TSLP Recombinant Human Thymic Stromal Lymphopoietin (TSLP); TSLP recombinant protein

• Host: E Coli
• Form/Format: Human TSLP was Lyophilized from a 0.2 um filtered concentrated (1.0mg/ml) solution in 20mM PB, pH7.4, 150mM NaCl.

• Applicable Applications for TSLP recombinant protein: Cell Assay
• Species: Human
• Endotoxin Level: <1.0EU/ug of recombinant protein as determined by the LAL method.
• Reconstitution: A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1mg/ml. This solution can then be diluted into other buffers.
• Preparation and Storage: The lyophilized protein is stable for at least one year from date of receipt at -70 degree C. Upon reconstitution, this cytokine can be stored in working aliquots at 2 degree -8 degree C for one month, or at -20 degree C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Activity

(Sample Cell Assay Data: The ED(50) was determined by the dose-dependent proliferation of human IL-7R-alpha and human TSLP R co-transfected mouse BaF3 cells, was found to be < 3.0 ng/mL.)

SDS-Page

(Purity: Recombinant Human TSLP resolved on a 15% SDS-PAGE gel under reducing conditions and stained with Coomassie Brilliant Blue G-250)

Related Product Information for TSLP recombinant protein

Recombinant Human TSLP was expressed in E Coli cells. The protein accession number is Q969D9
TSLP is a hemopoietic protein that was initially identified from mouse thymic stromal cell line that promoted the development of B cells. TSLP overlaps biological activities with IL-7 and can co-stimulate growth of thymocytes and mature T cells alongside supporting lymphopoiesis. Human TSLP shares approximately 43% amino acid sequence identity with mouse TSLP. Human TSLP has been detected in many tissues although the highest level of expression has been found in the heart, liver, testis and prostate. TSLP signals through a heterodimeric receptor complex that consists of IL-7R-alpha and the TSLP-R.

NCBI Description

This gene encodes a hemopoietic cytokine proposed to signal through a heterodimeric receptor complex composed of the thymic stromal lymphopoietin receptor and the IL-7R alpha chain. It mainly impacts myeloid cells and induces the release of T cell-attracting chemokines from monocytes and enhances the maturation of CD11c(+) dendritic cells. The protein promotes T helper type 2 (TH2) cell responses that are associated with immunity in various inflammatory diseases, including asthma, allergic inflammation and chronic obstructive pulmonary disease. The protein is therefore considered a potential therapeutic target for the treatment of such diseases. Alternative splicing of this gene results in multiple transcript variants.
