Primary Amine
A polyamine-based Ambion® siRNA transfection agent that can be used to transfect cells during subculturing-—saving a full day of valuable time—without increasing toxicity. It is supplied in one tube containing 0.4 mL. A successful siRNA experiment requires the appropriate transfection agent for your cells, and one that is optimized for siRNA delivery. The efficiency with which different transfection reagents deliver nucleic acids can vary dramatically with the type of nucleic acid being transfected (RNA vs. DNA, single-stranded vs. double-stranded) and the cells being used.

The Alexa Fluor 488 Oligonucleotide Amine Labeling Kit provides a simple method for labeling amine-modified oligonucleotides with our bright, photostable, green-fluorescent Alexa Fluor 488 dye (which is spectrally similar to fluorescein). Oligonucleotides labeled with this kit can be used as primers and as probes in hybridization experiments but should not be used for automated DNA sequencing since the Alexa Fluor dye in the kit is supplied as mixed isomers. The kits have been optimized for labeling reactions with 50 µg of a 5'-amine—modified oligonucleotide, 18 to 24 bases in length.

Properly controlled IHC stains require that a non-immune immunoglobulin equivalent of the primary antibody be run on the sample tissue in the same way that the primary antibody is run. Any positive staining would indicate that the primary antibody stain may not be specific. These reagents can be used as negative isotype controls for our predilute primary antibodies.

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.

The amine-reactive Alexa Fluor 430 carboxylic acid, succinimidyl ester and its conjugates exhibit the rare combination of absorption between 400 nm and 450 nm and fluorescence emission beyond 500 nm (excitation/emission maxima ~434/539 nm).

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.

Pacific Green™ Succinimidyl Ester is a violet-excitable (411 nm) dye with an emission maximum at ~500 nm, allowing it to be used with other violet-excitable fluorophores (such as Pacific Blue™ or Pacific Orange™ dye) for multiparameter analysis using a single excitation source. As a class of compounds, succinimidyl esters offer an efficient and easy-to-use means for selectively linking a dye to accessible primary amine groups on proteins, modified nucleic acids, or other biomolecules. The covalent bonds formed are as stable as the peptide bonds used to link the amino acids within proteins. Pac...
