Product Description	Recombinant Human TSLPR Protein is expressed from HEK293 with hFc tag at the C-Terminus.It contains Gly25-Lys231.
Product Background	Thymic stromal lymphopoietin (TSLP) is an interleukin-7 (IL-7) like cytokine, which plays an important role in the regulation of immune responses to allergens. TSLP binds to a heterodimeric receptor complex composed of the IL-7 receptor alpha chain (IL-7Ralpha) and the TSLP receptor (TSLPR, also known as CRLF2).
Product Category	Recombinant Protein / Antibody discovery / Antibody discovery \| Others

Protein	TSLPR
Synonyms	TSLP receptor; TSLPR; CRL2; CRLF2Y; CRLF2; IL-XR; p2RY8/CRLF2 fusion; CRLF2
Accession	Q9HC73-1
Species	Human
Biotinylated	no
Amino Acid Range	Gly25-Lys231
Molecular Weight	The protein has a predicted MW of 50.8 kDa. Due to glycosylation, the protein migrates to 60-75 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human TSLP (R127A, R130A), His Tag at 2ug/ml (100ul/Well). Dose response curve for Human TSLPR, hFc Tag with the EC50 of 4.0ng/ml determined by ELISA (QC Test). The affinity constant of 1.04 nM as determined in SPR assay (Biacore T200). See testing image for detail.
Product Tag	C-hFc
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1 EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage	-20 to -80°C for 24 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
