Interpolated concentrations of native PD-L2 in human PBMC cell culture supernatant samples stimulated or unstimulated with PHA/PMA.

The concentrations of PD-L2 were measured in duplicates, interpolated from the PD-L2 standard curves and corrected for sample dilution. Undiluted samples are as follows : unstimulated 100% and stimulated 100%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean PD-L2 concentration was determined to be 32 pg/mL in stimulated PBMC cell culture supernatant and undetectable in unstimulated and media controls.

Product details

Human PD-L2 ELISA Kit, Chemiluminescent (ab326305) is a rapid single-wash sandwich 55-min ELISA to measure Human PD-L2 in Serum, Plasma – Citrate, Plasma – EDTA, Plasma – Heparin, Cell Culture Supernatant, Urine, Saliva, Milk with a sensitivity of 1.23 pg/mL.

How the assay works

Human PD-L2 ELISA Kit, Chemiluminescent (ab326305) SimpleStep Ignite™ 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 during a 30 min only incubation, significantly reducing assay time. By utilizing a chemiluminscent detection method this improves the sensitivity and dynamic range when compared to traditional colorimetric ELISAs.

Assay Specificity

Our SimpleStep Ignite™ 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.
