Product Specifications Data Sheet

About The Somru® Exendin-4 ELISA kit is a competitive ELISA that designed to measure exendin-4 with high specificity and enhanced sensitivity in human plasma. The assay utilizes high affinity antibody against exendin-4 measure exendin-4 without any significant interference from other components of human plasma.
Detection method Colorimetric; absorbance at 450 nm with reference absorbance at 650 nm.
Storage Store the unopened kit at 2-8 °C.
Safety Warnings and Precautions All chemicals should be considered potentially hazardous. We recommend that this product and its components be handled by those trained in laboratory techniques and be used according to the principles of Good Laboratory Practice.
Quality Control Samples (QCs)

 

 Three levels of QCs are included for custom GLP kits for an additional cost.  QCs are prepared by fortifying exendin-4 in human plasma or serum.
Precision

 

 The precision was determined by analyzing samples prepared at 200 pg/mL in 6 replicates on 6 different occasions. Intra-assay precision (coefficient of variation (CV)) ranges from 9% to 15%. Inter-assay precision was at 14%.
Accuracy/ Recovery 200 pg/mL of exendin-4 was fortified in 10 lots of human serum.  Recovery ranges are from 89-102% with an average recovery of 97%.
Total Error Total Error (TE) was calculated by adding the mean %bias with inter-assay variability (%CV). The TE was found to be less than 21%.
Sensitivity The limit of detection is 156 pg/mL.
Dilutional Linearity Dilutional linearity was tested up to 10 fold dilution
Hook Effect Not applicable for competitive assay.
Specificity/ Cross-reactivity
Analyte             % Cross-reactivity
Exendin-4 (3-39) 100%
Exendin-3 100%
Glucagon 0%
Oxyntomodulin 0%
Sample Pre-treatment (ADA Interference) If a high level of anti-exendin-4 antibody is expected to be present in test samples, an acid dissociation step may be incorporated to minimize  the impact of these antibodies in exendin-4 quantitation.
