Protein Labeling Reagents
Santa Cruz Biotechnology Chromeo™ P503 | 1mg
Chromeo™ P503 detects proteins and peptides by exhibiting a color change from blue to red. After binding to primary amines, it undergos a large shortwave spectral shift of more than 100nm that is visible to the naked eye. There is also a large increase in quantum yield that changes the non- or only weakly fluorescent dye into a bright fluorescent conjugate. The shift of the absorption & emission bands together with the increased fluorescence quantum yield effectively eliminates background from any unbound dye. In addition, because unbound the pyrylium dye is hydrolyzed during the labeling procedure, there is no need for purification following the simple one-step, room-temperature incubation. The labeled protein is ready to use immediately, and any possible background from the unbound dye is eliminated. Due to the unique conjugation mechanism, proteins labeled with Py-Dyes maintain their native charge and isoelectric point.
Dojindo Molecular Technologies Inc PlasMem Bright Green dye (100 ul) offers plasma membrane staining for 24 hrs+ with clear visualization, high retentivity, low toxicity, water-soluble, no washing, applicable to live and fixed cells.
The plasma membrane consists of a lipid bilayer separating the intracellular environment from the extracellular space. Thus, the PM plays a central role in many cell behaviors such as cell migration, cell stretching, and signaling cascades. Additionally, PM dysfunction is an important biomarker because it is related to cell status and is linked to many diseases. PlasMem Bright dyes have higher retentivity on the plasma membrane. Furthermore, PlasMem Bright dyes are more water-soluble compared with other commercially available dyes and can be diluted with the culture medium. The PlasMem Bright dyes offer two different color options (green and red) and provide ready-to-use DMSO solutions. A working solution can be prepared easily via a single dilution step using growth medium or HBSS. Dojindo offers various reagents for cell membrane research.

LICOR IRDye 800CW Azide Infrared Dye (50 mg)
IRDye 800CW Azide provides the functionality for preferential labeling of molecules that contain either the alkyne or dibenzocyclooctyne (DBCO) group.
LICOR IRDye 750 Maleimide Infrared Dye ( 0.5mg)
IRDye 750 Maleimide is an infrared dye with detection near 750 nm. Maleimide reactive group provides the functionality for labeling molecules that contain free sulfhydryl (–SH thiol) groups. This reactive group allows conjugation reactions to be performed at physiological pH. This dye is not suitable for use with LI-COR Odyssey Imaging Systems.
AdipoGen Fluorescein dioctadecanoate
Chemical. CAS 920269-51-8. Formula C56H80O7. MW 865.23. Fluorescein dioctadecanoate is a non-fluorescent hydrophobic fluorescein derivative that can pass through the cell membrane whereupon intracellular esterases hydrolyze the dioctadecanoate group producing the highly fluorescent product fluorescein. The fluorescein molecules accumulate in cells. Fluorescein dioctadecanoate is a fluorogenic substrate for C18 esterase that generates green fluorescence upon esterase cleavage. Spectral Data lambdaEx 497nM, lambdaEm 516nm. Extinction coefficient 80000 cm-1 M-1.
