Product Specifications Data Sheet

About The Somru® Erythropoietin ADA ELISA kit is a dual detection sandwich assay for the determination of antibodies against erythropoietin in serum and plasma samples. Assay employs acid charcoal pre-treatment of samples to improve detection of anti-erythropoietin antibodies and to improve drug tolerance.
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 and biological samples should be considered potentially hazardous and infectious. 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.
Positive control Rabbit/ Goat anti-erythropoietin fortified in human serum. Check lot specific Certificate of Analysis (CofA) for details.


The precision was determined by analyzing samples prepared at 500 ng/mL in 6 replicates on 6 different occasions. Intra-assay precision (coefficient of variation(CV)) ranges from 5% CV to 10%CV. Inter-assay mean precision precision was at 14%CV.
Sensitivity The detection limit is 37 – 118 ng/mL depending on the positive control used.
Drug Tolerance The drug tolerance is up to 4000 pg/mL.
Sample Pre-treatment An acid charcoal treatment to remove insulin and erythropoietin from sample highly recommended to improve drug tolerance and the detection of ADAs in biological samples. Please contact our technical service team at
Interpretation of results The results are interpreted as positive or negative relative to a pre-determined cut point.  The cut point may be determined in each plate by running 4-10 negative controls. The cut point is calculated by calculating the mean of the negative controls and by adding 2*standard deviations to the calculated mean.
Statistical cut point We strongly recommend each lab develop their own statistical cut point in the appropriate study population using methodologies as described by G. Shankar, et al. (2008). (Recommendations for the Validation of Immunoassays Used for Detection of Host Antibodies Against Biotechnology Products. J. Pharmaceutical and Biomedical Analysis 48:1267–1281).  Please contact our technical service team at  for details.


Notice: Somru® ELISA kits are custom-made to order. Each kit lot is tested to ensure that it meets specifications before shipment. Minor adjustments to the preparation of reagents may occur due to lot-to-lot variation. Please always refer to the product sheet enclosed with each kit before performing each experiment.
