Fluorescent labeling Service

Fluorescent labeling technology refers to the covalent binding or physical adsorption of fluorescent substances on a chemical group of molecule to be studied, and the subsequent qualitative, and quantitative analyses of the labeled objects by observing fluorescence characteristics.

Fluorescent labeling has several advantages i.e. it does not cause radioactive contamination, easy to operate, and easy to observe under fluorescent microscope, etc. Fluorescent labelling has great potential in studying proteins, nucleic acids, cell biology and performing immuno-analyses. The application of fluorescent labeling has been deeply involved in many fields such as pharmacology, physiology, environmental science, and information sciences, etc., and has been widely used in the functional research of proteins and drug screening.

MCE has an efficient, experienced and professional technical team who can chemically incorporate fluorescent labels on biomolecules, proteins, antibodies, and peptides. We can offer variety of labels and conjugates to choose from and multiple customization services less to microgram level. Furthermore, we can meet all relevant needs of customers regarding fluorescent labelling.

1. Fluorescent labeling service does not guarantee activity. Antibody labeling services do not affect antibody activity and more than 95% of protein labeling services do not affect protein activity.
2. Conjugation leads to depletion. The recovery of small molecule labeling usually varies from 5% to 60%. For 50-100 μg protein labeling service, recovery is over 90%, for 500 μg or more protein labeling service, recovery is over 98%.
3. There is a risk of failure for small molecule labeling, and a partial fee will be charged if failed.
