R-M-5429	Carboxyrhodamine 110 PEG4 Acid	Carboxyrhodamine 110 also known as Rhodamine Green™ Carboxylic Acid. The amine-reactive Carboxyrhodamine 110 LC can be used to create bright and photostable green-fluorescent bioconjugates with excitation/emission maxima ~502/527 nm. For many applications, the dye is preferred over carboxyfluorescein or FITC because of its exceptional photostability and fluorescence insensitivity to pH (4-9).This reagent is supplied as Boc protected derivative to ensure compatibility with Fmoc solid phase peptide synthesis. The hydrophilic spacer arm contains a hydrophilic, 4-unit, polyethylene glycol (PEG) group imparts water solubility of the labeled peptide resulting in less aggregation when stored in aqueous solution. Spacers of different lengths are available upon request.	price>
R-M-5432	PB-PEG4-Acid	PB dye (Pacific Blue™ equivalent) is a bright, blue-fluorescent dye optimally excited by the 405 nm line of the violet laser and with excitation/emission at 410/455 nm. The excitation and emission spectrum of PB dye offers minimal overlap with green fluorophore emission spectra, making it an ideal choice for the first violet channel. Conjugates of this dye are strongly fluorescent even at neutral pH.(PB-PEG4-Acid)The hydrophilic spacer arm contains a hydrophilic, 4-unit, polyethylene glycol (PEG) group imparts water solubility of the labeled peptide resulting in less aggregation when stored in aqueous solution. Spacers of different lengths are available upon request.	price>
