ELISA protein standards
Protein standards are critical components used to ensure the accuracy and reliability of ELISA/immunoassays.

Protein standards are pre-determined, known concentrations of proteins that are used to create a calibration curve against which unknown sample data are compared, allowing researchers to quantitatively measure the amount of specific antigens or proteins present in biological samples. Our ELISA protein standards are designed for high reproducibility to enhance the performance of both research and diagnostic assays.
We provide protein standards for human/mouse or rat targets. Our protein standards are:
- Recombinantly expressed in E. coli or HEK 293 cells.
- Validated in sandwich ELISA (with our antibody pairs) and SDS-Page.
- Provided as 10 μg in a liquid format with a concentration of ~1 mg/mL (exact concentration is batch dependent).
Main advantages of our recombinant protein standards:
- Consistent and scalable production: using recombinant expression ensures minimal lot-to-lot variability and security of supply.
- Tested with our recombinant monoclonal antibody pairs, they are the perfect companion to design your immunoassay with confidence.
- A guaranteed purity of > 80% verified by SDS-Page makes them suitable for immunoassay design.
Our recombinant protein standards complement our antibody pairs by providing fully characterized materials that ensure accurate calibration and reliable quantification in immunoassays.
