GelRed® is an ultra sensitive, extremely stable and environmentally safe fluorescent nucleic acid dye designed to replace the highly toxic ethidium bromide (EB) for staining dsDNA, ssDNA or RNA in agarose gels or polyacrylamide gels. GelRed® is far more sensitive than EB without requiring a...

Biotin TCO (trans-cyclooctene) reacts with tetrazine containing molecules via copper free click chemistry. This copper free bioorthogonal reaction is useful for labeling live cells, or when there are concerns about native protein function loss with copper in cell extracts.

DiOC₂(3) (3,3'-Diethyloxacarbocyanine, iodide) has been used for measuring membrane potentials in bacteria. The green fluorescent dye forms red fluorescent aggregates with increasing membrane potential. The spectral shifting phenomenon has been exploited to measure membrane potential...

The trimethoprim-PEG3-amine (TMP-PEG3-amine) can be conjugated to various probes to make trimethoprim-based chemical tag (TMP-tag). The TMP-tag is based on the high affinity (K_d ~ 1 nM) binding of TMP to the E.coli dihydrofolate reductase (eDHFR). The target protein, fused to eDHFR via...

This product is prepared by labeling highly cross-adsorbed donkey anti-mouse IgG (H+L) with CF®633 dye.
