Background of TRANCE/TNFSF11/RANK L

Receptor activator of nuclear factor kappa-B ligand (RANKL), also known as tumor necrosis factor ligand superfamily member 11 (TNFSF11), is a protein that in humans is encoded by the TNFSF11 gene. This gene encodes a member of the tumor necrosis factor (TNF) cytokine family which is a ligand for osteoprotegerin and functions as a key factor for osteoclast differentiation and activation. This gene is mapped to chromosome13q14.11. Targeted disruption of the related gene in mice led to severe osteopetrosis and a lack of osteoclasts. The deficient mice exhibited defects in early differentiation of T and B lymphocytes, and failed to form lobulo-alveolar mammary structures during pregnancy. This gene may play an important role in enhanced bone-resorption in humoral hypercalcemia of malignancy.

Recommended Sample Dilution Ratios

According to our internal validation assays using this ELISA kit, to detect TRANCE/TNFSF11/RANK L, Dilution ratio of 1:1, concentration in serum and plasma is less than the lowest standard, 78 pg/ml..

Some articles we found to cite concentrations of TRANCE/TNFSF11/RANK L in samples: 22057136 (Pubmed IDs).

Intra Assay Consistency & Inter Assay Consistency

We measured random samples of Human TNFSF11/RANKL ELISA Kit PicoKine® within the same batch/lot to ensure the consistency of the kits' performances. ELISA intra assay consistency is measured using wells from the same plate/assay kit. ELISA inter assay consistency is measured using wells from different plates from the same batch production/lot.
