Antibodies to the Druggable Genome

Abgent’s core focus on development of antibodies against regulatory enzymes, beginning with the design and manufacture of antibodies against over 1000 epitopes spanning the human kinome, has resulted in an extensive antibody portfolio against a broad cross-section of proteins comprising the druggable genome.  We have expanded on this selection of pharma-centric antibody products and announce a comprehensive collection of over 200 qualified antibodies targeting druggable proteins.  New protein targets in this collection include: EIF4B, EIF4E, HGF, VEGF1, VEGF2, VEGF3, STK11, MAPK1, MAPK3, and PI3KCB, PI3KR1, PI3KCG and PI3KR5.

Autophagy APG16L Antibodies – Marker for Crohn Disease

antibodyAbgent’s autophagy antibodies are directed against human homologs of proteins indentified in the autophagy process, including APG16L, a member of the APG12-APG5-APG16L complex, which plays a role in the formation of the autophagosome. A genome-wide association scan of nonsynonymous SNPs has identified a susceptibility variant for Crohn disease in ATG16L. Drs. J. Hampe, S. Schreiber, P. Rosenstiel et al. used Abgent’s APG16L antibody (Catalog No. AP1817b) on a patient biopsy to confirm colonic Crohn disease.

Q: Can you give me some tips to aid design of my peptide epitope for my polyclonal antibody project?

A: Peptide sequence is crucial to creating an antibody that will specifically recognize native proteins with high affinity. We usually use peptides that are 12 to 20 amino acids in length. The following are useful tips for modifying your peptide sequence to assist in solubility, synthesis and/or purification. (1) Minimize difficult amino acids such as multiple Cys, Met, Arg, or Trp in the sequence. (2) Minimize hydrophobic amino acids or break up a string of hydrophobic amino acids with a polar amino acid. (3) Avoid N-terminal glutamic acid so that it cannot cyclize to form pyroglutamine. (4) The peptide sequence must be selected from an accessible region of the protein. The trans-membrane region of a protein is not usually exposed and should thus be avoided. Similarly, any region that undergoes post-translational modification (e.g. glycosylation), should also be avoided, since antibodies raised against this sequence may not recognize the modified native protein. (5) Synthetic peptides should be able to adopt a conformation that mimics its structure within the protein. (6) Multiple glutamines should be avoided, since they may cause insolubility by forming hydrogen bonds between the peptides.
Please consult our FAQ section for further peptide design tips.
