产品详情

Human IL-1ra ELISA Kit ab211650 is a rapid single-wash 90-min Sandwich ELISA to measure Human IL-1ra in cell culture extracts, cell culture supernatant, milk, plasma, saliva, serum, tissue extracts, urine. This SimpleStep sensitivity is 1.5 pg/mL.

How the assay works

Human IL-1ra SimpleStep ELISA®employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.

Assay Specificity

Our SimpleStep ELISA® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

Human IL-1ra ELISA Kit ab211650 protocol summary

1. Mix: add samples/standards to the wells together with the capture and detector antibody cocktail. Incubate 1 hr at room temperature
2. Wash
3. Add TMB development solution - incubate for 10 min
4. Add Stop solution
5. Read the results on a plate reader at 450 nm

Save your precious samples

Our 384-well Human IL-1ra ELISA Kit only requires a maximum of 12.5µL sample

Design your own immunoassay

We offer the antibody pair used in this kit in a BSA and Azide-free format, ready for conjugation:

- Anti-IL-1RA antibody [EPR18693-54] - BSA and Azide free (Capture) ab242974
- Anti-IL-1RA antibody [EPR18693-60] - BSA and Azide free (Detector) ab242974

Interleukin-1 receptor antagonist (IL-1ra, also known as IL-1F3) is a member of the IL-1 cytokine family. IL-1ra inhibits the activity of interleukin-1 by binding to receptor IL1R1 and preventing its association with the coreceptor IL1RAP for signaling. However, IL-1ra has no interleukin-1 like activity. It binds functional interleukin-1 receptor IL1R1 with greater affinity than decoy receptor IL1R2; however, the physiological relevance of the latter association is unsure.
