Amino-11-dCTP has the base modification in 5-position of pyrimidine to introduce primary amine groups via enzymatic reaction. The resulting DNA molecule allows further labeling with amino-reactive reagents.
Modified nucleotides, e.g. deoxycytidine triphosphates (dCTP), are commonly for the incorporation into DNA a functional group, not originally available in the nucleotide structures. Amino-11-dCTP possesses longer linker of 11 atoms for the amino group.

This reagent is a cost-efficient way to perform high throughput protein quantitation in well plates. This reagent is recommended for quantitating purified protein or antibody samples when performing many experiments daily with the same calibration. The ProteOrange dye has low tolerance to non-ionic detergents, and is not recommended for use with cell lysates containing Triton X-100, sodium deoxycholate. The assay can tolerate up to 0.01% SDS (in final concentration).
The unique structure of the ProteOrange reagent allows accurate detection of proteins in solutions with concentrations between 10 ng/mL and 10 µg/mL . This level of sensitivity is considerably better than that achieved with the BCA method, Bradford assay, Lowry assay, or absorption measurements at 280 nm.

QuDye Protein Quantification Reagent is designed for quantification of protein concentration by a fluorometer in the range of initial protein concentration from 12.5 to 5000 µg/mL. The reagent can be used for quantification of protein concentration with both fluorescence microplate readers and cuvette-based fluorometers, whose measurement range can be wider, depending on the characteristics of the device. Because the reagent selectively binds to SDS-protein micelles, the presence of nucleotides, DNA, RNA, amino acids, salts, reducing agents (2-mercaptoethanol, DTT), and other impurities (except detergents) in the sample does not affect the result of measurement. QuDye Protein Quantification Reagent is quite versatile and allows quantification of the concentration of various proteins with high sensitivity.
This product is a component of QuDye Protein Quantification Kit and is used as an OEM component of kits by other manufacturers.

DOTA-PEG4-amine contains a terminal amino group, DOTA (1,4,7,10-Tetraazacyclododecane-1,4,7,10-tetraacetic acid) moiety, and a linear PEG chain as a linker. It is widely used for bioconjugation in the imaging diagnostics field due to the DOTA possessing chelating properties, and a highly reactive amine group.
The hydrophilic PEG chain increases the aqueous solubility. PEG linker allows to incorporate the chelating agent by conjugation of DOTA-PEG4-amine with carboxylic acids and activated esters using even sterically hindered moieties in a biomolecule.
