Proprietary biomarker assays

Enzyme-Linked Immunoassay (ELISA)

The ELISA sphingotest® penKid® represents a product expansion of SphingoTec’s reference assay technology and enables the quantitative measurement of Proenkephalin A 119–159 (penKid). The assay was developed to closely match the performance of SphingoTec’s chemiluminescence reference assay while allowing use on standard laboratory photometers. This format enables straightforward implementation in clinical and research laboratories and provides investigators with reliable access to penKid measurement for scientific and translational studies.

Immunoluminometric Assay

SphingoTec’s reference assays are based on acridinium ester chemiluminescence sandwich immunoassay technology and enable the quantitative measurement of the proprietary biomarkersProenkephalin A 119–159 (penKid) and bioactive Adrenomedullin 1–52 (bio-ADM). This technology has been used to analyze more than 100,000 clinical samples across more than 200 studies and serves as the analytical reference standard for calibration and correlation of licensed assays such as AFIAS sphingotest® penKid® and product expansions including the ELISA sphingotest® penKid®.
