Sigma Aldrich Fine Chemicals Biosciences Sera MagTM Magnetic carbox
Sera-Mag(TM) SpeedBeads(TM) and Sera-Mag(TM) Carboxylate-Modified Magnetic Particles combine a fast magnetic response time and high binding capacity with a large surface area high sensitivity stability physical integrity and fast reaction kinetics. Covalent coupling of biomolecules such as proteins and nucleic acids to carboxyl groups on the surface is easily accomplished using our standard coupling technology. The core of the particle is made by a free radical emulsion polymerization of styrene and acid monomer. One (Sera-Mag(TM)) or two (Sera-Mag(TM) SpeedBeads(TM)) layers of magnetite are then coated onto this core while the surface is modified to minimize non-specific binding of proteins.

Biotium CF568 succinimidyl ester
CF Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Red fluorescent CF568 dye has excitation/emission at 562/583 nm.
Biotium CF405S Tyramide
CF dye tyramide conjugates can be used for tyramide signal amplification (TSA), which is an enzyme-mediated detection method that uses horseradish peroxidase (HRP) to generate high-density labeling of a target protein or nucleic acid in situ. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Blue fluorescent CF405S dye has excitation/emission at 404/431 nm.Also see Biotium's CF Dye Tyramide Amplification Kits.
