Human TSLP R Protein, Fc Tag

  • Synonym
    TSLP R,CRLF2,IL-XR,ILXR,p2RY8,CRLF2 fusion,TSLP receptor,TSLPR,CRL2,CRLF2Y,Cytokine receptor-like 2
  • Source
    Human TSLP R, Fc Tag(TSR-H525a) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Lys 231 (Accession # Q9HC73-1).
    Predicted N-terminus: Gly 25
  • Molecular Characterization
    TSLP R Structure

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 50.4 kDa. The protein migrates as 60-65 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
TSLP R SDS-PAGE

Human TSLP R, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).

  • Background
    Receptor for thymic stromal lymphopoietin (TSLP). CRLF2 / TSLPR is a member of the type I cytokine receptor family. Together with the interleukin 7 receptor (IL7R) and TSLP activate STAT3, STAT5, and JAK2 pathways, which control processes such as cell proliferation and development of the hematopoietic system.
