Bungarotoxins are venom toxins from the many-banded krait (Bungarus Multicinctus), which inhibit neurotransmission at the neuromuscular junction. Alpha-bungarotoxin is a potent inhibitor for the motor endplate acetylcholine receptor (Kd = 1 nM to 1 pM). Beta-bungarotoxin contains a small subunit that blocks voltage-gated K+ channels on the presynaptic membranes, and a large subunit that has phospholipase A2 activity. Fluorescent conjugates of alpha-bungarotoxin can be used to label acetylcholine receptors in skeletal muscle endplates.

CF® Dyes with a BCN group react with azides via a copper-free bioorthogonal reaction to label target molecules for surface staining of live cells or cell extracts. Membrane-permeant CF® Dye BCN conjugates for intracellular labelling reactions are also available.

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.

CF® dye picolyl azide reacts with alkyne to form 1,2,3-triazole by 1,3-dipolar Huisgen cycloaddition through the use of a much lower copper (I) concentration without sacrificing reaction efficiency. The selected CF® dyes are exceptionally bright and photostable, making them the perfect dye for fluorescence detection.

Aqua 431 [DEAC] dUTP is a coumarin derivative that 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 labelled probes can be prepared with this fluorescent nucleotide by a variety of methods including nick translation, random prime labelling, cDNA labelling and 3’-end labelling. 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. Aqua 431 dUTP can also be used for multicolor fluorescence labelling.

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.
