products description :
Principle of the Assay: This experiment use double-sandwich elisa technique and the ELISA Kit provided is typical. The pre-coated antibody is Mouse KL monoclonal antibody and the detecting antibody is polyclonal antibody with biotin labeled. Samples and biotin labeling antibody are added into ELISA plate wells and washed out with PBS or TBS. Then Avidin-peroxidase conjugates are added to ELISA wells in order; Use TMB substrate for coloring after reactant thoroughly washed out by PBS or TBS. TMB turns into blue in peroxidase catalytic and finally turns into yellow under the action of acid. The color depth and the testing factors in samples are positively correlated.

ncbi summary :
This gene encodes a type-I membrane protein that is related to beta-glucosidases. Reduced production of this protein has been observed in patients with chronic renal failure (CRF), and this may be one of the factors underlying the degenerative processes (e.g., arteriosclerosis, osteoporosis, and skin atrophy) seen in CRF. Also, mutations within this protein have been associated with ageing and bone loss. [provided by RefSeq, Jul 2008]
uniprot summary :
Klotho: May have weak glycosidase activity towards glucuronylated steroids. However, it lacks essential active site Glu residues at positions 239 and 872, suggesting it may be inactive as a glycosidase in vivo. May be involved in the regulation of calcium and phosphorus homeostasis by inhibiting the synthesis of active vitamin D. Essential factor for the specific interaction between FGF23 and FGFR1. Defects in KL are a cause of hyperphosphatemic familial tumoral calcinosis (HFTC). A severe metabolic disorder that manifests with hyperphosphatemia and massive calcium deposits in the skin and subcutaneous tissues. Some patients manifest recurrent, transient, painful swellings of the long bones associated with the radiographic findings of periosteal reaction and cortical hyperostosis and absence of skin involvement. Belongs to the glycosyl hydrolase 1 family. Klotho subfamily. 2 isoforms of the human protein are produced by alternative splicing. Protein type: EC 3.2.1.31; Membrane protein, integral; Hydrolase. Chromosomal Location of Human Ortholog: 13q12. Cellular Component: extracellular space; integral to plasma membrane; integral to membrane; extracellular region; plasma membrane. Molecular Function: vitamin D binding; signal transducer activity; fibroblast growth factor binding; beta-glucosidase activity; beta-glucuronidase activity; hormone activity; fibroblast growth factor receptor binding. Biological Process: calcium ion homeostasis; epidermal growth factor receptor signaling pathway; phosphoinositide-mediated signaling; fibroblast growth factor receptor signaling pathway; nerve growth factor receptor signaling pathway; carbohydrate metabolic process; insulin receptor signaling pathway; energy reserve metabolic process; innate immune response; positive regulation of bone mineralization; acute inflammatory response; aging. Disease: Tumoral Calcinosis, Hyperphosphatemic, Familial
