Our Biotin Labeling Capabilities
We provide professional biotin labeling and biotin conjugation services for peptides, proteins, antibodies, small molecules and oligonucleotides. We design site-specific biotin modification schemes according to your research requirements, with strict quality control and full characterization reports delivered.
Small Molecule Biotin Tagging
Custom synthesis of biotin-linked small molecule probes for drug screening and biological interaction research.
Protein & Antibody Biotin Conjugation
Mild biotin labeling conditions are adopted to retain the natural biological activity of proteins and antibodies.
Oligonucleotide Biotin Modification
Biotin labeling of DNA / RNA probes, widely used in hybridization, pull-down and biosensor assays.
Peptide Biotin Labeling
Site-specific biotin modification on peptides, including N-terminal, C-terminal and amino acid side-chain labeling.
Frequently Asked Questions
Find answers to frequently asked questions about our custom biotin labeling and chemical synthesis services.
-
What types of samples can you perform biotin labeling for?
We support biotin modification of peptides, proteins, antibodies, small molecules and oligonucleotides.
-
Is site-selective biotin labeling available?
Yes. We will design a suitable labeling scheme based on your molecular structure and experimental goals.
-
What is the typical lead time for biotin labeling projects?
Normally 1–2 weeks, the schedule depends on the complexity of your target molecule.
Will biotin modification affect the bioactivity of my protein?
We use mild reaction systems to minimize damage to the biological activity of proteins and antibodies.
-
What purity standard can you guarantee for biotinylated products?
Our standard specification is HPLC purity ≥95%, higher purity requirements are negotiable.
