3rd Annual Peptides Congress, London

April 18th-19th, 2016
London, UK

Scientific discussions about the current results and future challenges of peptides research and therapeutics will be the main topic of this meeting.

Furyl-Alanine: A Novel Photo-Click Amino Acid

2-Furyl-alanine can be incorporated into peptides via SPPS or by using enzymatic approaches. UV-irradiation in the presence of oxygen and a photosensitizer converts furyl-alanine to an intermediate that selectively reacts with certain nucleophiles. This property can be employed for site-specific labeling of peptides and proteins.

Targeted and Reversible Biotinylation with Biotin-SS-Tyramide

Our new Biotin-SS-Tyramide linker is a valuable tool for peroxidase-promoted targeted protein biotinylation. By using peroxidase-tagged antibodies, proteins and protein clusters can be selectively biotinylated, and then isolated using streptavidin. The biotin tag can be subsequently removed using reducing agents (e.g. glutathione).

Fmoc-Phe-Aca: Fluorescent Internalization Reporter for Cell Penetrating Peptides (CPPs)

The Fmoc-L-Phe-Aca pseudo-dipeptide is a useful reporter group for the successful internalization of CPPs. Phe quenches the fluorescence of Aca. Internalization of the peptide containing Phe-Aca leads to proteolytic cleavage of the Phe-Aca bond and thus to fluorescence.

3rd Belgian Peptide Group Meeting

February 17th-18th, 2016
Brussels, Belgium

This meeting intends to cover various aspects in peptide world: drug discovery and development, pharmacology, structure-activity relationship, drug delivery, synthesis, identification and characterization.

23èmes Journées Jeunes Chercheurs

February 15th-17th, 2016
School of Pharmacie, Lille, France

Iris Biotech GmbH will be present during the talks and supports the organisation with a booth at the Industrial Exhibition. We are pleased to get in personal contact with you.

Inexpensive & High Quality Guanylation Reagents

We now offer N,N'-Bis-Boc-N"-triflylguanidine, at both a very competitive price and our habitual high quality. Find out about the usefulness of this and our other guanylation reagents!

Siderophore Building Block: New Hydroxamate-Ornithine for Fmoc/tBu SPPS

N^δ-hydroxy-N^δ-acetyl-ornithine, an important constituent of many siderophores, is now available for your convenience as N^α-Fmoc-N^δ-(acetyl)-N^δ-(benzoyloxy)-ornithine building block which can be used in standard Fmoc/tBu SPPS and permits facile on-resin N^δ-deprotection.

Click Chemistry Tools: Propargyl Amino Acids

Click chemistry is a convenient method to chemoselectively functionalize peptides at specific positions. We offer a variety of different propargyl amino acids for both Fmoc and Boc strategies, for enzymatic synthesis, as well as preloaded resins for SPPS.

Canalin and Canavanine : New Fmoc building blocks for novel peptides and protein analogs

5-oxa-Derivatives of Orn and Arg, respectively, these rare amino acids are produced by legumes as protection against herbivores. For your convenience, we offer building blocks of both amino acids compatible with standard Fmoc/tBu SPPS chemistry
