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.

Carboxyl coupling resin consists of 6% cross-linked agarose with covalently linked diaminodipropylamine (DADPA) to generate a free primary amine at the end of a long spacer arm. Molecules, including proteins, peptides and nucleic acids, are covalently coupled to the free primary amines, and the stable columns are ideal for affinity purification of antibodies and other interacting partners.

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.

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.

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.
