Rhodamine 110 Label Rhodamine 110 proved to be a very suitable label for fluorescent protease assays. The red-shifted excitation (492nm) and emission (529nm) shows better signal-to-noise ratio and

2. Ubiquitin & Derivatives

Ubiquitin & Derivatives The small protein ubiquitin plays an important role in a variety of cell processes, e.g. in degradation of misfolded proteins, in signal transduction, and regulation of

3. Special Building Blocks

... Cysteine analogs (Cys(Pys), Cys(NPys), Bunte salt) PEG building blocks Fatty acids &...

4. Fluorescently Labeled Protease Substrates

Fluorescently Labeled Protease Substrates Coumarin Based Substrates Typically, fluorescence-based protease assays use peptide amidomethylcoumarin derivatives as substrates. The non-fluorescent

5. Synthesis of Standard Peptides

Synthesis of Standard Peptides BIOSYNTAN offers automated custom synthesis of peptides up to 100 residues on a scale of 1-500 mg, purification (standard purities: 80% or 95%) and analysis of all

6. Phosphorylation

Phosphorylation Phosphorylation of peptides is one of the most frequently occurring post-translational modifications of peptides and proteins. Phosphorylation/dephosphorylation plays a key roll in

7. Glycosylation

Glycosylation Glycosylation represents another important type of post-translational modification. Glycans serve a variety of structural and functional roles in membranes and secreted proteins.

8. D-Amino Acids

D-Amino Acids Opposite stereochemistry in the α-position of essential amino acids produces interesting new features. Firstly, D-amino acids increase the stability of peptides against

9. Cyclization & Disulfides

Cyclization & Disulfides Cyclic peptides exhibit interesting features compared to the linear species: such peptides are remarkably stable against degradation by proteases. Furthermore, they can

10. Overview

Fluorescently Labeled Peptides BIOSYNTAN has gained great expertise in fluorescent labeling of peptides over many years. Our portfolio includes various fluorescent labels and different labeling
