Your chance for breaking discoveries

Our high-dens­ity pro­tein arrays present over 15,000 human pro­teins and pep­tides derived from dif­fer­ent tis­sues. The cor­res­pond­ing cDNA expres­sion lib­rar­ies were val­id­ated, and advanced in more than 15 years of exper­i­ence. The com­bin­a­tion of estab­lished, pub­lished and well-char­ac­ter­ized anti­gens and neoanti­gens enables you to dis­cov­er nov­el bio­mark­ers hypo­thes­is-free and unbiased.

Unique coverage of human proteome

High con­tent of >15,000 full-length anti­gens, pro­tein iso­forms & pep­tides, neoanti­gens & frameshift pep­tides.

Largest neoantigen library

Enzymatic modification

Invest­ig­ate if cit­rul­lin­a­tion, phos­phoryla­tion or car­bamyl­a­tion are dis­ease-asso­ci­ated or caus­at­ive. Our pro­tein arrays can be mod­i­fied enzymat­ic­ally. For example, rheum­at­oid arth­rit­is autoantibod­ies are usu­ally dir­ec­ted against cyc­lic cit­rul­lin­ated pep­tides.

What our customers say

“To identi­fy poten­tial bio­mark­ers asso­ci­ated with axi­al spon­dyloarth­rit­is, we used the engine bio­mark­er screen­ing ser­vice. As a first step, we had the autoantibody pro­files of 4 patients invest­ig­ated. In the course of this invest­ig­a­tion on Uni­PEx arrays, more than 50 poten­tial anti­gens could be iden­ti­fied. A subar­ray was cre­ated for these can­did­ates and in a second step, a lar­ger num­ber of patients could eas­ily be testet. This allowed us, to fur­ther nar­row down our poten­tial bio­mark­er can­did­ates. These will now be val­id­ated in fur­ther stud­ies on a dif­fer­ent plat­form. The engine pro­tein arrays are a great tool for broad bio­mark­er screen­ing in the field of autoim­mune dis­eases. The engine team has sup­por­ted us through­out the pro­cess and the screen­ing ser­vice has allowed us to focus on our oth­er pro­jects in par­al­lel with the test­ing.”
