Protein linking and labelling systems provide a convenient means for attaching fluorescent labels or biotins to antibodies and larger proteins. These kits are ideal for use with multiple applications, including flow cytometry, fluorescent microscopy, immunohistochemistry, primary detection, ELISAs, immunocytochemistry, and FISH. These systems are available with a variety of dye colours, biotin, fluorescent agents, and all the components needed to perform multiple conjugations and purifications. Protein labelling follows a simple protocol of reaction, separation, and then use.

CF™ dye bovine serum albumin conjugates
Supplier: Biotium
Fluorescent bovine serum albumin (BSA) conjugates are commonly used as tracers in applications where physical dimensions are important. The conjugates can also be used for quantitative studies of electroporation, measurement of plasma volume in rats, and endocytosis studies. CF™ dye BSA conjugates are labelled with fluorescent CF™ dyes, which offer advantages in brightness and photostability compared to other fluorescent dyes.

Lipophilic carbocyanine dyes and CellBrite cytoplasmic membrane labelling kits
Supplier: Biotium
Carbocyanine dyes with long hydrocarbon chains have low fluorescence in aqueous phase, but become highly fluorescent upon binding to lipid bilayers, making this class of dyes ideal for staining cell membranes. Carbocyanine dye membrane staining is very stable, with minimal dye transfer between cells. Dilinoleyl carbocynaine dyes have much faster lateral diffusion rates than regular carbocyanine dyes, which facilitates labelling of neurons in tissues.

IgG Biotinylation kits, HOOK™
Supplier: G-Biosciences
HOOK™ IgG biotinylation kits are designed for the biotinylation of IgG molecules by immobilising the IgG molecules on a solid support. Nickel chelating resin allows for the rapid removal of uncoupled biotin and therefore eliminates the need for further dialysis or desalting of the biotinylated antibody.

Orange 552 dUTP
Supplier: ENZO LIFE SCIENCES
Orange 552 dUTP (5-TAMRA-dUTP) can replace TTP in reactions in which it serves as a substrate for E. coli DNA polymerase (holoenzyme and Klenow fragment), T4 and Taq DNA polymerases, reverse transcriptase (from AMV and M-MuLV) and terminal transferase. Fluorescently labeled probes can be prepared with this fluorescent nucleotide by a variety of methods including nick translation, cDNA labeling and 3’-end labeling. Probes generated by these methods are suitable for use for the identification of specific sequences by in situ hybridization procedures on fixed cells and tissues by direct fluorescence detection. Orange 552 dUTP can also be used for multicolor fluorescence labeling.

Wheat germ agglutinin (WGA) conjugates
Supplier: Biotium
A wheat germ agglutinin (WGA) lectin labelled with Biotium’s CF® Dyes or HRP. It is a carbohydrate-binding lectin that has high affinity for sialic acid and N-acetylglucosamine moieties of glycoproteins. As a result, WGA conjugates will label yeast bud scars and the cell membrane of gram-positive bacteria and mammalian cells.
