Human ngal duoset elisa kit

Manufactured by R&D Systems

The Human NGAL DuoSet ELISA kit is a laboratory assay designed to quantitatively measure the levels of the protein NGAL (Neutrophil Gelatinase-Associated Lipocalin) in human samples. The kit provides the necessary components to perform a sandwich enzyme-linked immunosorbent assay (ELISA) for the detection and quantification of NGAL.

Human NGAL DuoSet ELISA kit (R&D, catalog# DY1757, lot# P195696) was employed in the study. Specifically, 100 μl of serial diluted standard samples (PART#842273) as well as urinary samples from patients and self-described healthy volunteers (10-fold dilution using reagent diluent) were added into different wells and the plate was incubated at room temperature for 2 hours. The plate was washed subsequently and incubated with biotinylated detection antibodies (PART#844865, 25 ng/ml in reagent diluent) for 2 hours, washed again with PBST, and incubated with HRP-labeled streptavidin (PART#893975, 40-fold dilution using reagent diluent) for 20 mins. Human NGAL p-FLISA was performed by adopting a similar procedure as the ELISA with significantly shortened assay time. Specifically, the incubation time for standards/samples, biotinylated detection antibodies, 800CW-labeled streptavidin (LI-COR P/N 926-32230, 50 ng/ml), and plasmonic-fluor-800CW (extinction~1) was set to 5 minutes. The study was approved by Washington University IRB 201601082 “Nanotech Biomarkers for Renal Cancer Intervention: Clinical Validation and Utility” and IRB 201202051 “Urine Proteome of Surgical Patients and Healthy Volunteers”. Informed consent was obtained from the participants.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
