other info2 :
Intended Uses: This ELISA kit is intended for laboratory in vitro research use only, not for drug, household or other use! The Stop Solution changes the color from blue to yellow and the intensity of the color is measured at 450 nm by a spectrophotometer. In order to measure the concentration of Human KL in the sample, this ELISA kit includes a set of calibration standards. The calibration standards are assayed at the same time as the samples and allow the operator to produce a standard curve of Optical Density versus Human KL concentration. The concentration of Human KL in the samples is then determined by comparing the O.D. of the samples to the standard curve. Intra-assay Precision: Intra-assay CV (%) are less than 15%. Inter-assay Precision: Inter-assay CV (%) are less than 15%.

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: Hydrolase; EC 3.2.1.31; Membrane protein, integral. 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-glucuronidase activity; beta-glucosidase activity; hormone activity; fibroblast growth factor receptor binding. Biological Process: epidermal growth factor receptor signaling pathway; calcium ion homeostasis; fibroblast growth factor receptor signaling pathway; phosphoinositide-mediated signaling; nerve growth factor receptor signaling pathway; carbohydrate metabolic process; energy reserve metabolic process; insulin receptor signaling pathway; innate immune response; positive regulation of bone mineralization; acute inflammatory response; aging. Disease: Tumoral Calcinosis, Hyperphosphatemic, Familial
