Labelling

Pyrene azide 2 is a compound derived from pyreneacetic acid, connecting a fluorescent pyrene molecule by a PEG2 linker. The PEG units improve the water solubility of the compound.

Cyanine7.5 carboxylic acid is a water soluble, near infrared fluorescent dye with a free, unactivated caboxylic acid group.

Texas Red, also known as sulforhodamine 101 acid chloride, is a red-fluorescent dye employed for cell staining, fluorescence microscopy, and cell sorting using fluorescent-activated cell sorting machines.

Cy7 diacid is a near-infrared fluorescent dye containing two non-activated, free carboxylic acid groups.

Cy7 diacid is a near-infrared fluorescent dye containing two non-activated, free carboxylic acid groups.

BP Fluor 647-PEG10-azide is a water-soluble, far-red fluorescent probe with excitation ideally suited for the 633 nm or 647 nm laser lines. A significant advantage to using long wavelength dyes such as Cy5 or BP Fluor 647 dye over other fluorophores is the low autofluorescence of biological specimens in this region of the spectrum. The azide reacts with strained cyclooctynes such as BCN, DBCO via a copper-free "click chemistry" reaction. The brightness and photostability of this dye are best suited to direct imaging of low-abundance targets. The PEG10 enhances water-solubilty and fines tunes the biological activity of the labeled products.

BP Fluor 647 carboxylic acid is a bright green-fluorescent dye optimal for use with the 633, 650 nm Argon laser. The compound's sulfonate groups permit hydrophilicity and less aggregation in the aqueous solution. BP Fluor 647 is used for protein and antibody labeling, or nucleic acid applications with high labeling density. The carboxyl group can react with amines via coupling agent (e.g. HATU).

1-(pentan-5-dipropylamine)-1-hydroxyl-1,1-bis(TBDMS-hexane)

TCO-PEG3-PB is a click chemistry fluorescent dye containing a tetrazine-reactive TCO moiety and pacific blue moiety which has an excitation wavelength of 410 nm and emission maxima of 455 nm.
