SOMAscan

Choosing the Right Biomarker Discovery Tool

A high-level comparison of two of the most promising proteomic technologies — mass spectrometry and the SOMAscan assay

A Breakthrough Proteomics Platform for the Life Sciences Community

The SOMAscan assay – the most powerful protein biomarker discovery tool available today – includes more than 1,300 different SOMAmer reagents (current version). Access to the SOMAscan assay is on a simple fee-for-service basis, although some applications will require a deeper collaborative relationship.

The latest version of the SOMAscan assay (SOMAscan Assay 1.3k) measures greater than 1,300 protein analytes in only 150 µl of several different biological matrices.***

The assay offers exceptional dynamic range, quantifying proteins that span over 8 logs in abundance (from femtomolar to micromolar) and excellent reproducibility (4.6% median %CV).

Process for submitting and analyzing samples

After a SOMAscan assay service agreement is in place, the project manager assigned to your project will send you a Sample Submission Form. This form is to be completed and submitted along with the samples. Upon arrival at our facility, the samples are checked to ensure that they have arrived in good condition with all the necessary information. At that point, the study is entered into the SOMAscan assay queue. The samples are assayed, the data are normalized as appropriate and all project documentation is reviewed by our Quality Assurance team. The data are typically delivered within 5 weeks of sample receipt. Historically, our turnaround time is 34 days.
