Product Summary

This DuoSet ELISA Development kit contains the basic components required for the development of sandwich ELISAs to measure natural and recombinant human beta-NGF. 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: beta-NGF

Nerve growth factor (NGF) was initially isolated in the mouse submandibular gland over three decades ago as a 7S complex composed of three non- covalently linked subunits, alpha, beta, and gamma. It is now known that both the alpha and gamma subunits of NGF are members of the kallikrein family of serine proteases, while the beta subunit, called beta-NGF or 2.5S NGF, exhibits all the biological activities ascribed to NGF. The human protein shares approximately 90% identity at the amino acid level with both mouse and rat beta-NGF.

Long Name:	beta Nerve Growth Factor
Entrez Gene IDs:	4803 (Human); 18049 (Mouse); 310738 (Rat); 403402 (Canine); 103350089 (Rabbit)
Alternate Names:	Beta nerve growth factor precursor; beta-nerve growth factor; betaNGF; beta-NGF; HSAN5; MGC161426; nerve growth factor (beta polypeptide); nerve growth factor, beta subunit; NGFB; NGFBMGC161428

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.
