Protein Expression Services

Protein expression services are opening for the University of Debrecen from May 2012.

Recombinant Human IL-4

Recombinant human IL-4 is available for purchase either in the form of IL-4 containing culture medium (use 1:10 dilution) or in purified form. The protein is produced in HEK293T cells, batch-tested by Western blotting, ELISA, TF-1 proliferation assay, and against endotoxins. See product sheet. Please, order online.

Polyclonal anti-SMRT antibody

Rabbit polyclonal anti-SMRT antibody is available for purchase. The antibody is protein-A purified, Western, IP, IHC, ChIP tested. See product sheet.

The aim of the project
The aim of the project is to develop an antibody designing algorithm which is based on structural information, to optimal and create antibody prototypes which are able to recognize native protein antigens, and therefore, they application is wider range, and their efficiency and reliability are much better than nowadays products.
Recombinant proteins are widely used in present-day medical biology. Antibodies are one of the most important tools used in the analysis of proteins. Nowadays antibodies are extensively used in research, pathological diagnostics as well as in therapy. Not only antibodies, but cytokines are also one of the most important reagent-family in immunology and stem cell research, and their therapeutic application is also extensive.
Our goals:
1. University of Debrecen aims to establish a research laboratory facility which is able to fast react in high quality and produce the necessary quantities of required antibodies and cytokines to meet local as well as international needs.
2. To establish novel epitope design algorithm in antibody development based on structural biological information, with the help of which it will be possible to create high affinity antibodies in an innovative way.
3. To develop labelled cytokines which can be traced in biological systems, and thereby to generate a new subtype of the reagent family.
Members of consortium
1. University of Debrecen
2. UD-GenoMed Medical Genomic Technologies Kft.
