Vector Laboratories Neurobiotin™ Tracer for Neuronal Cell Tracing 50 mg
NEUROBIOTIN™ Tracer 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. NEUROBIOTIN™ Tracer can be used in many types of preparations including in vivo, whole mounts, slice preparations, or cultured cells. It can be delivered by many routes such as intracellular electrodes, microinjection, cutloading, or scrape-loading, and can be detected using avidin or streptavidin systems with either chromogenic or fluorescence visualization methods.

Medchemexpress LLC Cy3 NHS ester | 1393363-07-9 | 99.5% | 590.15 | 50 MG
Cy3 NHS ester is a CY dye. CY, short for Cyanine, is a compound consisting of two nitrogen atoms connected by an odd number of methyl units. Cyanine compounds have characteristics of long wavelength, adjustable absorption and emission, high extinction coefficient, good water solubility, and relatively simple synthesis. CY dyes are often used for the labeling of proteins, antibodies, and small molecular compounds. For the labeling of protein antibodies, the combination can be completed through a simple mixing reaction.
- Long wavelength
- Adjustable absorption and emission
- High extinction coefficient
- Good water solubility
- Relatively simple synthesis
- Used for labeling of proteins, antibodies, and small molecular compounds
