The cell-permeant SYTO 82 orange fluorescent nucleic acid stain exhibits bright, orange fluorescence upon binding to nucleic acids. Because the staining pattern of the SYTO dyes in live cells may vary between cell types, we offer the SYTO Orange Fluorescent Nucleic Acid Stain Sampler Kit (S-11360) to enable researchers to find the most appropriate orange-fluorescent SYTO stain for their system.

DTNB or Elman's reagent can be used to quantitate thiols in proteins, cells and plasma by absorption measurements. It readily forms a mixed disulfide with thiols, liberating the chromophore 5-merapto-2-nitrobenzoic acid (absorption maximum 410 nm). Only protein thiols that are accessible to this water-soluble reagent are modified.

Tetrafluorophenyl (TFP) esters are an improvement over the succinimidyl ester (SE or NHS-ester) chemistry typically used to attach fluorophores or haptens to the primary amines of biomolecules. Both reactive chemistries produce the same strong amide bond between the dye or hapten and the compound of interest, but TFP esters are less susceptible to spontaneous hydrolysis during conjugation reactions. Alexa Fluor TFP esters are stable for several hours at the basic pH typically used for reactions – far outlasting succinimidyl esters.

Acid Phenol:Chloroform:IAA (125:24:1) is premixed and supplied at pH 4.5 ± 0.2. Provided in one bottle of 400 mL. In RNA extraction procedures, Acid Phenol:Chloroform:IAA aids in the removal of DNA (it partitions into the organic phase), helps to stabilize the interface, and prevents foaming when mixing. Preparation of phenol for use in molecular biology applications is a time-consuming and often hazardous procedure due to its toxic and corrosive nature. Ambion® premixed, quality-tested, saturated phenols are ready to use, eliminating handling problems and offering a more convenient, safer, an...

This single 5-isomer preparation of our proprietary, amine-reactive dye, Oregon Green 488 carboxylic acid, succinimidyl ester and its conjugates have green fluorescence similar to that of fluorescein but are more photostable. Additionally, Oregon Green 488 dye has a lower pK a than fluorescein (pK a = 4.7 versus 6.4 for fluorescein), making this bright dye less pH sensitive in the physiological range.

To permit simultaneous long-term tracing of mixed-cell populations using different fluorescent colors, we have developed a probe whose applications should be similar to those of CFDA SE (commonly called CFSE). Cells labeled with our SNARF-1 carboxylic acid, acetate, succinimidyl ester have orange-red fluorescence that can be easily distinguished from that of cells loaded with green-fluorescent tracers such as CFDA SE.

Molecular Probes® cholera toxin conjugates are made from a recombinant version of the B subunit only. This allows us to provide a very high-purity product that is completely free of the toxic A subunit. Cholera toxin B subunit (CT-B) attaches to cells by binding to ganglioside G M1 , making it a powerful tool for retrograde labeling of neurons. This tracer has been used in a variety of applications, including tracing of rat forebrain afferents, projections of the parabrachial region, and neurons of the urinary bladder wall. When used in neuronal tracing applications, CT-B is typically introduc...
