You searched for: Protein Linking and Labeling Systems
Protein linking and labeling 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 colors, biotin, fluorescent agents, and all the components needed to perform multiple conjugations and purifications. Protein labeling follows a simple protocol of reaction, separation, and then use.
Biotin-20-dUTP, Biotium
Supplier: Biotium
Biotin-20-dUTP can be enzymatically incorporated into DNA via nick translation, random priming, or 3′-end terminal labeling. Biotin-dUTP conjugates are available wtih 11-carbon, 16-carbon, or 20-carbon linker lengths.

HRP WGA Wheat Germ Agglutinin (WGA) Conjugates
Supplier: Biotium
A wheat germ agglutinin (WGA) lectin labeled 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.

CF®DI Aminooxy, Biotium
Supplier: Biotium
CF®DI aminooxy dyes react with aldehyde/ketone groups on proteins or other biomolecules to form a stable oxime bond. The CF®DI dyes (CF®488DI, CF®555DI and CF®647DI) are designed to match each other for molecular weight and charge. The molecular weights of the same protein conjugated to different CF®DI dye colors are close to each other and the pl of the labeled proteins remains the same.
