|0.5 mg/mL of mouse anti-FGFR4 monoclonal antibody (in PBS, pH 7.4). Dilute to a working concentration of 2 μg/mL in CBS before coating.|
|0.25 mg/mL rabbit anti-FGFR4 polyclonal antibody conjugated to horseradish-peroxidase (HRP) (in PBS, 50 % glycerol, pH 7.4). Dilute to working concentration of 0.5 μg/mL in detection antibody dilution buffer before use.|
|Each vial contains 42 ng of recombinant FGFR4. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve using 2-fold serial dilutions in sample dilution buffer, and a high standard of 2 ng/mL is recommended.|
|The minimum detectable dose of Human FGFR4 / CD334 was determined to be approximately 31.25 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.|
|The Human FGFR4 / CD334 ELISA Pair Set is for the quantitative determination of Human FGFR4 / CD334.|
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for FGFR4 / CD334 coated on a 96-well plate. Standards and samples are added to the wells, and any FGFR4 / CD334 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-FGFR4 / CD334 polyclonal antibody is then added, producing an antibody-antigen-antibody "sandwich". The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of FGFR4 / CD334 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
|Capture Antibody: Aliquot and store at -20℃ to -80℃ for up to 6 months from date of receipt. Avoid repeated freeze-thaw cycles.|
Detection Antibody: Protect it from prolonged exposure to light. Aliquot and store at -20℃ to -80℃ and for up to 6 months from date of receipt. Avoid repeated freeze-thaw cycles.
Standard: Store lyophilized Standard at -20℃ to -80℃ for up to 6 months from date of receipt. Aliquot and store the reconstituted Standard at -80℃ for up to 1 month. Avoid repeated freeze-thaw cycles.
Fibroblast growth factor receptor 4 (FGFR4) also known as CD334 antigen or tyrosine kinase related to fibroblast growth factor receptor, is a member of the fibroblast growth factor receptor family, where amino acid sequence is highly conserved between members and throughout evolution. FGFR family members differ from one another in their ligand affinities and tissue distribution. A full-length representative protein would consist of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of FGFR4/CD334 interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. FGFR4/CD334 preferentially binds acidic fibroblast growth factor and, although its specific function is unknown, it is overexpressed in gynecological tumor samples, suggesting a role in breast and ovarian tumorigenesis. FGFR4/CD334 signaling is down-regulated by receptor internalization and degradation; MMP14 promotes internalization and degradation of FGFR4/CD334. Mutations in FGFR4/CD334 lead to constitutive kinase activation or impair normal FGFR4 inactivation lead to aberrant signaling.
