Cambridge Science Park, outside the SeraDiag laboratory

About

A specialist biospecimen supplier, and a manufacturer

SeraDiag supplies characterised human biospecimens to IVD manufacturers and pharmaceutical researchers, and designs and manufactures recombinant antigens and disease models in house. Both sides of that answer the same question: what material does your assay need, and can you get it again next year?

What we do

Two capabilities, one problem

Assay developers run out of material. Either it does not exist at the titre you need, or the lot you validated on cannot be repeated.

01

Biospecimens

Disease-state serum, plasma and clinical remnants collected ethically through our clinical network.

02

Recombinant antigens

Designed, expressed and purified by our team.

03

Disease models

Isogenic models carrying a single pathogenic variant, edited at the endogenous locus.

All of our material is collected ethically and traced from donor to dispatch under our ISO 9001 quality system. We will always tell you plainly whether a native clinical sample or a made-to-order model is the right fit for your programme.

Where we are

Cambridge and London

Our laboratory sits at 25 Cambridge Science Park, where processing, characterisation and storage all happen in one place. Material does not pass through hands we do not control.
