Biotins & Derivatives
The streptavidin-biotin interaction, at a dissociation constant of (Kd) on the order of ~10-14 mol/L is one of the strongest non-covalent interactions known in nature, typically occurring between a protein and a ligand.
The complex is resistant to pH, organic solvents and other denaturing agents making this interaction very stable and hence attributes to its importance in a number of biological applications including Western blotting, IHC, ELISA and FACS.
Phycobiliproteins are natural fluorescent proteins present in cyanobacteria and some algae.
B-PE and the closely related R-PE are the most intensively fluorescent ones. They are significantly brighter and more photostable than conventional organic dyes.
Protein A binds to the Fc domain of IgG’s from most mammals. When conjugated to biotin or fluorescent dyes, it can be used as a universal detection reagent for primary antibodies.
Our offer also includes Albumens like BSA and OVA conjugated to biotins and fluorescent dyes useful in cellular imaging/tracking, immune & binding assays, and drug delivery applications.
Nucleic Acid Labeling & Fluorescent Nucleotides
Nucleic acid (NA) quantitation by using fluorescent dyes offer an accurate and sensitive way of NA quantitation via a variety of nucleic acid stains. These stains can be used for DNA quantitation in solutions or in cells.
In addition, reagents for labeling nucleotides and nucleic acids are also part of our comprehensive collection of NA reagents including fluorescent nucleotides.
Synthetic & Natural Enzyme Substrates
Several fluorogenic synthetic and natural enzyme substrates are used in the accurate and quick measurement or screening of enzyme activities in various cellular and extracellular applications.
Some include collagen, elastin, resorufins etc.
