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.

Wheat germ agglutinin (WGA) conjugates

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.

Fluorescein-12-ddUTP

Fluorescein-12-ddUTP

Supplier: ENZO LIFE SCIENCES

Fluorescein-12-ddUTP can be used for 3’-end labeling of oligodeoxynucleotides using terminal transferase. It also serves as a substrate for E.coli DNA Polymerase I (holoenzyme and Klenow fragment), T4 and T7 DNA polymerases, Taq DNA polymerase and reverse transcriptase. Oligonucleotide probes labelled with fluorescein-12-ddUTP can be detected by direct fluorescence detection (green fluorescence) or by methods using horseradish peroxidase- or alkaline phosphatase-linked anti-fluorescein antibodies.

Bio-16-ddUTP, tetralithium salt

Bio-16-ddUTP, tetralithium salt

Supplier: ENZO LIFE SCIENCES

Bio-16-ddUTP (Biotin-16-2’,3’-dideoxyuridine-5’-triphosphate) can be used for 3’-end labelling of single-stranded or double-stranded DNA. It is especially useful as a substrate for terminal transferase for the 3’-terminal addition of a single Bio-16-ddUMP. Biotin-labelled oligonucleotides produced by this reaction are suitable as hybridisation probes and nucleic acid array assays. It is also a substrate for Taq DNA polymerase and other DNA polymerases.
