Lucifer Yellow CH dilithium salt is a water-soluble, high-intensity fluorescent tracer containing a hydrazide functional group. It is used for intracellular injection, neuronal morphology visualization, gap junction coupling studies, and other applications that require a polar, membrane-impermeant fluorescent probe.
- High fluorescence intensity for sensitive detection.
- Water-soluble formulation for easy dissolution in aqueous buffers.
- Excitation ~428-430 nm and emission ~536-540 nm for common fluorescence setups.
- Hydrazide group enables reaction with aldehydes for covalent labeling.
- Solid, yellow to orange appearance suitable for handling and storage.
- High purity (HPLC) for reproducible experimental performance.

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.
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

Enzo Life Sciences BIO-PROBE 3'-Oligonucleotide labeling kit with bio-16-ddUTP (25Reactions)
Terminal labeling is an ideal procedure for the labeling of oligonucleotides with haptens such as biotin or fluorescein. An oligonucleotide can be synthesized using standard, commercially available reagents and labeled after synthesis in a simple and reproducible enzyme reaction.The BIO-PROBE 3'-Oligonucleotide Labeling Kit with Bio-16-ddUTP contains all reagents required for terminal labeling of oligonucleotides with biotin except the oligonucleotides to be labeled. The BIO-PROBE 3'-Oligonucleotide Labeling Kit provides maximum flexibility for labeling oligonucleotides approximately 15 to 100 nucleotides in length. A standard reaction will label up to 100 picomoles (1 µg of a 30-mer oligonucleotide sequence). A complete kit contains two component packs that are available separately: a Reagent Pack and a Bio-16-ddUTP Dideoxynucleotide Pack. Both packs contain sufficient reagents for 25 labeling reactions. Applications: Southern Blot, Northern Blot, ISH , Dot Blot.
