Human Total PDGF R beta DuoSet IC ELISA Summary

Product Summary

This DuoSet IC ELISA contains the basic components required for the development of sandwich ELISAs to measure total PDGF R beta in cell lysates. An immobilized capture antibody specific for PDGF R beta binds both phosphorylated and unphosphorylated PDGF R beta. After washing away unbound material, a biotinylated detection antibody is used to detect both phosphorylated and unphosphorylated protein, utilizing a standard Streptavidin-HRP format.

Preparation and Storage

Background: PDGF R beta

PDGF R beta is a transmembrane receptor tyrosine kinase (RTK) that primarily binds to the PDGF-BB isoform of the growth factor. Ligand binding induces receptor homodimerization or heterodimerization with PDGF R alpha followed by autophosphorylation and signal transduction. PDGF receptor signaling is attenuated by SHP-2 phosphatase activity and by receptor endocytosis and lysosomal degradation. The expression of the alpha and beta receptors is independently regulated in various cell types. A soluble splice variant of PDGF R beta binds PDGF with high affinity and functions as a potent PDGF antagonist.

Assay Procedure

Refer to the product datasheet for the complete assay procedure.

Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.

1、Prepare all reagents, standard dilutions, and samples as directed in the product insert.

2、Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

3、Add 50 μL of Assay Diluent to each well.

4、Add 50 μL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.

5、Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.

6、Add 100 μL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.

7、Aspirate and wash 5 times.

8、Add 100 μL Substrate Solution to each well.

9、Add 100 μL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
