Vector Laboratories Biotin (Long Arm) Hydrazide, 50 mg
Specialty Products. Biotin (Long Arm) Hydrazide reacts with aldehyde groups and thus can be used to label carbohydrate groups present in a wide variety of macromolecules. The spacer arm in this product allows optimal accessibility of avidin or streptavidin conjugates to biotin. Incorporation of Biotin (Long Arm) Hydrazide involves a two-step process. First, the saccharide is treated with periodate (not included) that produces aldehyde groups on sugars containing unsubstituted vicinal hydroxyl groups (these are usually present at the non-reducing termini of the oligosaccharide). Next, Biotin (Long Arm) Hydrazide reacts with the aldehyde groups to produce a stable linkage between the saccharide and biotin. This reagent can also be used to couple biotin to carboxyl groups on proteins and other molecules using a carbodiimide coupling method, and to specifically label RNA with biotin at the 3' end.
Cayman Chemical SureLIght488 NHS ester 100ug
SureLight™ 488 is a bright green fluorescent dye with excitation suited to the 488 nm laser line, fluorescent microscopy, and flow cytometry. The NHS ester version is an efficient amine reactive probe that can be used to label proteins, antibodies, haptens, and other primary amine containing molecules.[Columbia Biosciences Product No. D44-100]
Vector Laboratories NEUROBIOTIN Tracer
NEUROBIOTIN Tracer (SP-1120) is an amino derivative of biotin that can be used as an intracellular label for cells, particularly neurons. It is used for visualizing neural architecture and for the identification of gap junction coupling. Can be used in many types of preparations including in vivo, whole mounts, slice preparations, or cultured cells - Can be delivered by many routes such as intracellular electrodes, microinjection, cut-loading, or scrape-loading - Can be detected using avidin or streptavidin systems with either chromogenic or fluorescence visualization methods

Biotium LysoView™ 633, 100uL
LysoView™ dyes are fluorescent stains for imaging lysosome localization and morphology in live cells. The dyes accumulate in the low pH environment of the lysosomes, resulting in highly specific lysosomal staining without the need for a wash step. Far-red fluorescent LysoView™ 633 exhibits pH-sensitive fluorescence (Ex/Em 634/659 nm at pH ≤5), further enhancing the specificity of staining.
