Thermo Scientific™ Alexa Fluor™ 420 NHS Ester (Succinimidyl Ester)
GREENER_CHOICE

Alexa Fluor 420 NHS Ester is an amine-reactive dye optimized for multiplex IHC and spatial biology. A long Stokes shift and 420/500 ex/em make it a good match for the CFP filter.

4

Invitrogen™ Alexa Fluor™ 350 NHS Ester (Succinimidyl Ester)

Used for stable signal generation in imaging and flow cytometry, Alexa Fluor™ 350 dye is water soluble and pH-insensitive from pH 4 to pH 10.

5

Invitrogen™ Alexa Fluor™ 488 C5 Maleimide

Alexa Fluor™ 488 is a bright, green fluorescent dye with excitation ideally suited to the 488 nm laser line.

6

Invitrogen™ Alexa Fluor™ 594 Hydrazide, for microinjection

Alexa Fluor™ 594 Hydrazide is useful as a cell tracer and as a reactive dye for labeling aldehydes or ketones in polysaccharides or glycoproteins.

9

Invitrogen™ Fluorescein biotin, 5-((N-(5-(N-(6-(biotinoyl)amino)hexanoyl)amino)pentyl)thioureidyl)fluorescein

5-((N-(5-(N-(6-(biotinoyl)amino)hexanoyl)amino)pentyl)thioureidyl)fluorescein (fluorescein biotin)
