HER3 / ErbB3 ELISA Pair Set, Human ELISA Pair Set

Fängerantikörper 0.1 mg/mL of mouse anti-ErbB3 monoclonal antibody, Dilute to a working concentration of 2 μg/mL in CBS before coating.

Nachweisantikörper 0.5 mg/mL of rabbit anti-ErbB3 monoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.25 μg/mL in detection antibody diluteion buffer before use.

Standard Each vial contains 80 ng of recombinant ErbB3. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -70℃ in a manual defrost freezer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 1500 pg/mL is recommended.

The minimum detectable dose of Human HER3 / ErbB3 was determined to be approximately 23.44 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 HER3 / ErbB3 ELISA Pair Set is for the quantitative determination of Human HER3 / ErbB3.

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 HER3 / ErbB3 coated on a 96-well plate. Standards and samples are added to the wells, and any HER3 / ErbB3 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-HER3 / ErbB3 monoclonal 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 HER3 / ErbB3 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.

Speicherung - Detection Antibody should be protected from prolonged exposure to light. Aliquot the reagents and store at -20℃ to -70℃ in a manual defrost freezer.

ErbB3, also known as Her3 (human epidermal growth factor receptor3), is a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. This membrane-bound glycoprotein has a neuregulin binding domain but has not an active kinase domain., and therefore can not mediate the intracellular signal transduction through protein phosphorylation. However, its heterodimer with ErbB2 or other EGFR members responsible for tyrosine phosphorylation forms a receptor complex with high affinity, and initiates the related pathway which lead to cell proliferation or differentiation. ErbB3 has been shown to implicated in numerous cancers, including prostate, bladder, and breast tumors. This protein has different isoforms derived from alternative splicing variants, and among which, the secreted isoform lacking the intermembrane region modulates the activity of membrane-bound form.
