Product Summary

This DuoSet ELISA Development kit contains the basic components required for the development of sandwich ELISAs to measure natural and recombinant rat GM-CSF. The suggested diluent is suitable for the analysis of most cell culture supernate samples. Diluents for complex matrices, such as serum and plasma, should be evaluated prior to use in this DuoSet.

Background: GM-CSF

GM-CSF (Granulocyte-Macrophage Colony Stimulating Factor) induces the development of monocytes, neutrophils, eosinophils, and myeloid and dermal dendritic cells. It also acts as a neutrophil and dendritic cell chemoattractant. GM-CSF promotes Th1 and Th17 cell mediated autoimmune inflammation as well as the inflammatory activation of dendritic cells, microglia, alveolar macrophages, and eosinophils. In addition, it cooperates with G-CSF in promoting tumor cell proliferation and invasion. GM-CSF signals through a receptor complex composed of GM-CSF R alpha and the Common beta Chain (beta c) with Syndecan-2 as a potential co-receptor. The beta c subunit is shared by the receptor complexes for IL-3 and IL-5.

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.

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

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

3Add 50 μL of Assay Diluent to each well.

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

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

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

7Aspirate and wash 5 times.

8Add 100 μL Substrate Solution to each well.

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