Protein Labeling Reagents
Biotium MTSEA Biotin-XX
MTSEA biotin selectively labels thiols under mild conditions. We offer MTSEA biotin with different linker lengths (Biotin-MTSEA, Biotin-X-MTSEA, and Biotin-XX-MTSEA), all of which allow selective labeling of cell surface thiols. Longer linkers should facilitate interaction between biotin and streptavidin. MTSEA biotin-XX: 2-((6-((6-((biotinoyl)amino)hexanoyl)amino)hexanoyl)amino)ethylmethanethiosulfonate; White solid soluble in DMF or DMSO; Store desiccated at -20°C; C25H45N5O6S3; MW: 607.7.

Sartorius pHrodo Orange Cell Labeling Kit, Real-Time Phagocytosis Quantification, Compatible With IncuCyte System, 1 Kit
The Sartorius IncuCyte pHrodo Orange Cell Labeling Kit provides a reliable solution for quantifying phagocytosis and efferocytosis using live-cell imaging. It features a unique pH-sensitive fluorophore that offers low fluorescence at neutral pH and a significant increase in fluorescence under acidic conditions. This enables real-time evaluation of cellular behaviors affected by various factors, setting it apart from other assays.
Biotium CellBrite™ Steady 488 Membrane Staining Kit | 100 labelings
CellBrite™ Steady Membrane Staining Kits allow fluorescence imaging of cell surface for up to several days in culture. The CellBrite™ Steady Dyes are unique fluorescent membrane probes that distribute between the cell surface and intracellular compartments, so cells retain cell surface staining over time. With the use of CellBrite™ Steady Enhancer, intracellular staining can be reduced or eliminated for imaging of cell outlines or boundaries.
Sigma Aldrich Fine Chemicals Biosciences Chromeo P503, 1 mg
Chromeo P503 is used as a fluorogenic reagent to label primary amine groups within molecules such as proteins. Chromeo P503 labeled proteins may be studied in a variety of gel electrophoresis and chromatographic applications.
Biotium Aminooxy-Biotin
Aminooxy-biotin can be used to covalently attach biotin to a molecule with an aldehyde or ketone group. The aminooxy group reacts with an aldehyde or ketone group to form a stable oxime linkage in an aqueous solution at neutral pH. The reaction is fast and can be further accelerated by adding aniline as a catalyst. Thus, aminooxy reagents are superior to hydrazide reagents, which also react with aldehydes or ketones but form unstable hydrazone linkages.
Biotium ViaFluor 488 Live Cell Microtubule Stain, Trial Size
ViaFluor™ 488 is a green fluorescent taxol probe with excitation/emission at 500/515 nm that allows fluorescent staining of microtubules in living cells for detection in the FITC channel. Supplied at 1000X in DMSO, with a vial of 100 mM verapamil, which can enhance staining in some cell types.
