    Product DescriptionUteroglobin

     

    Uteroglobin, also called Clara cell secretory, phospholipid binding, 10 kDa or 16 kDa protein (CCSP, CCPBP, CC10 or CC16, respectively) is a small, non-glycosylated secreted protein of the secretoglobin superfamily, (designated 1A, member 1). Its name is derived from its very high expression in the pre-implantation uterus. It is produced by the non-ciliated, non-mucous secretory cells that predominate in lung bronchioles (Clara cells), and other non-ciliated epithelia that communicate with the external environment. Expression is induced by steroid hormones such as estrogen, and enhanced by the non-steroid hormone prolactin. Uteroglobin is found in blood, urine and other body fluids. Human Uteroglobin cDNA encodes a 21 amino acid (aa) signal sequence and a 70 aa mature protein. It shares 53 - 56% aa identity with mouse, rat, bovine, canine, equine or rabbit Uteroglobin, and is active in mice. The mature protein forms a disulfide-linked head-to-tail homodimer of 16 kDa. This homodimer is thought to form a binding pocket that binds hydrophobic ligands such as phospholipids, progesterone and retinols. Sequestering of prostaglandins and leukotrienes is anti-inflammatory, while sequestering of carcinogens such as polychlorinated bisphenols is anti-tumorigenic. Other immunoregulatory activities of Uteroglobin include cell migration inhibition (by binding the chemotaxis-related formyl peptide receptor FPR2 on dendritic cells), and the inhibition of T cell differentiation to a Th2 phenotype. A single nucleotide polymorphism of Uteroglobin, A38G, confers increased risk of asthma. Transglutaminase can crosslink Uteroglobin, either to itself or to other proteins such as the adhesion molecule fibronectin. Binding of fibronectin to Uteroglobin in the kidney is thought to protect against nephropathy, while binding of the lipocalin-1 receptor has been reported to suppress cancer cell motility and invasion.

    Purity

    > 98% by SDS-PAGE and HPLC analyses.

    Biological Activity

    The ED50 as determined by the ability of the immobilized protein to support the adhesion of the A549 human lung carcinoma cells is less than 5.0 μg/ml, corresponding to a specific activity of > 200 IU/mg. Fully biologically active when compared to standard.

    Endotoxin

    < 0.1 EU per 1μg of the protein by the LAL method.

    Formulation

    Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4.

    Reconstitution

    We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions.

     

    Shipping and Storage

     

    The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.

    Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.

     

    Cautions

     

    Avoid repeated freeze-thaw cycles.

    For your safety and health, please wear lab coats and disposable gloves for operation.
