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...
Sulfation
Sulfation of peptides is another post-translational modification that occurs in some hormones and in malignant tissues. Particularly, the hydroxyl group of tyrosine is a prominent position...
Activated Cysteine Analogs
BIOSYNTAN offers peptides with pre-activated cysteine building blocks. Such pre-activated cysteine residues are excellent precursors for the formation of disulfide bonds.
Cl-Acetyl/Br-Acetyl/Maleimido Linker
Activated linkers are suitable tools to couple peptides to thiol groups of proteins or surfaces. BIOSYNTAN offers the following linkers for such purposes:
In...
Cyclization & Disulfides
Cyclic peptides exhibit interesting features compared to the linear species: such peptides are remarkably stable against degradation by proteases. Furthermore, they can...
Modified Peptides
Beyond the standard peptides, BIOSYNTAN offers custom synthesis of peptides with a huge variety of modifications, including posttranslational modifications, incorporation of ...
Spacer
BIOSYNTAN offers the following spacers in order to modify the distance between labels and epitopes, or to increase the solubility of your peptide.
We are able to incorporate a broad...
C-terminal Derivatization
Our C-terminal derivatization portfolio includes
C-terminal peptide hydrazides can easily be turned into azides, which can subsequently be used in ligation reactions.
