Intra-assay Precision (Precision within an assay): CV%<8%      
Three samples of known concentration were tested twenty times on one plate to assess.  
Inter-assay Precision (Precision between assays): CV%<10%      
Three samples of known concentration were tested in twenty assays to assess.    
To assess the linearity of the assay, samples were spiked with high concentrations of human FGF-23 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Q&A and Customer Reviews


I'd like to know if is possible performed the FGF 23 assay on plasma samples. Only on serum?

Thanks for your inquiry.
CSB-E10113h It is recommended to test the serum sample.
Plasma tests are not very effective. It is estimated that the presence of fibrinogen interferes with the test or the content of the plasma samples we collected is too low.Pls let me know if you have any further questions. Thank you.

I'd like to know if the kit CSB-E10113h recognizes C-terminal fragments or Intact FGF 23

Thanks for your inquiry.
The kit is designed for full-length, pls check the detailed information from this link: Pls let me know if you have any further questions. Thank you.

Target Data

Function Regulator of phosphate homeostasis. Inhibits renal tubular phosphate transport by reducing SLC34A1 levels. Upregulates EGR1 expression in the presence of KL (By similarity). Acts directly on the parathyroid to decrease PTH secretion (By similarity). Regulator of vitamin-D metabolism. Negatively regulates osteoblast differentiation and matrix mineralization.
Involvement in disease Hypophosphatemic rickets, autosomal dominant (ADHR); Tumoral calcinosis, hyperphosphatemic, familial (HFTC)
Subcellular Location Secreted
Protein Families Heparin-binding growth factors family
Tissue Specificity Expressed in osteogenic cells particularly during phases of active bone remodeling. In adult trabecular bone, expressed in osteocytes and flattened bone-lining cells (inactive osteoblasts).
