Fluorescein-12-UTP is ideal for in vitro transcription reactions catalysed by T3, T7, or SP6 RNA polymerases and reverse transcriptase to produce fluorophore-labeled RNA transcripts. RNA-based probes can be used to identify complementary sequences by in situ hybridisation to fixed cells and tissues by direct or indirect fluorescence detection or by membrane hybridisation procedures.

Red 650 [Cyanine-5E] dUTP is a cyanine-5 derivative with enhanced spectral properties. This nucleotide analog 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 labelling and 3'-end labelling.

This kit offers a set of three different monoclonal antibodies specific for threonine phosphorylation sites. Phosphorylation patterns in a given cell extract may differ when probed with different antibodies due to sequence specificity. Recognition therefore depends on two criteria: Phosphorylation and surrounding aa motif. If one of the two criteria is not fulfilled, the antibody will not detect the phosphorylation site.

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.

Phalloidin is a toxin isolated from the deadly Amanita phalloides mushroom. It is a bicyclic peptide that binds specifically to F-actin. Fluorescent conjugates of phalloidin are convenient tools to investigate the distribution of F-actin in fixed and permeabilised cells or tissue sections. One unit (U) of phallodin is sufficient to stain one sample (200 µl staining volume). A highly selective actin filament stain for fixed and permeabilised cells. Labeled phalloidins have similar affinity for both large and small filaments.

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.

Supplier: ENZO LIFE SCIENCES

This kit offers a set of seven different MAbs specific for tyrosine phosphorylation sites. Phosphorylation patterns in a given cell extract may differ when probed with different antibodies due to sequence specificity. Recognition therefore depends on two criteria: Phosphorylation and surrounding aa motif. If one of the two criteria is not fulfilled, the antibody will not detect the phosphorylation site. Specificity has been determined by epitope mapping using degenerated phosphopeptide libraries.

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.
