Biotin is a water-soluble member of the B-vitamin family with a molecular weight of 244 daltons
- Water-soluble member of the B-vitamin family
- Can be purified or detected using streptavidin
- Ideal alternative to many commonly used fluorophores
PromoFluor Dyes show a strong light absorptionas well as high fluorescence intensity and photostability, good pH insensitivity and water solubility. The superior quality of our PromoFluor dyes and a very reasonable price making them an ideal alternative to many commonly used fluorophores.
Biotin-labeled molecules can be purified or detected using streptavidin, NeutrAvidin or monomeric avidin. The biotin-streptavidin binding - taking place under physiological conditions - is one of the the strongest noncovalent biological interactions known and biotin is a very commonly used molecule for tagging of antibodies or other proteins. Thus, this fluorescent conjugates are making it easy to detect very sensitively various proteins which are widely used in bioanalytics.
