Various reagents designed to selectively label target proteins. Products include classic dyes, radioisotope labels, biotinylation reagents, fluorescent labels, molecular probes, assays, and labeling kits.
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.
Biotinylate reduced cysteines (-SH groups) at high pH via irreversible thioether bonds with this haloacetyl-activated, sulfhydryl-reactive biotinylation reagent.
Biotinylate reduced cysteines (-SH groups) at high pH with this haloacetyl-activated, sulfhydryl-reactive biotinylation reagent containing polyethylene glycol for solubility.
Biotinylate protein amines with this doubly-long-chain (30.5A), NHS-ester biotinylation reagent containing a membrane permeable spacer arm for intracellular labeling.
Biotinylate proteins or surfaces using EDC or other amine-reactive crosslinkers with a mid-length (22.9A) biotinylation reagent containing a 3-unit polyethylene glycol spacer.
Biotinylate protein amines with this cleavable, mid-length (24.3A), NHS-ester biotinylation reagent containing a reducible disulfide bond in the membrane-permeable spacer arm.
Biotinylate proteins or surfaces using EDC or other amine-reactive crosslinkers with this short (20.4A) biotinylation reagent containing a 2-unit polyethylene glycol spacer.
Biotinylate glycoproteins (aldehydes of oxidized sugars) with this mid-length (31.3A), pegylated biotinylation reagent containing a 4-unit PEG spacer for solubility.
Biotinylate protein amines with this cleavable, long (37.9A) NHS-ester biotinylation reagent containing a reducible disulfide bond in the pegylated, water-soluble spacer arm.
Biotinylate reduced cysteines (-SH groups) with a maleimide-activated, sulfhydryl-reactive biotinylation reagent containing a stabilizing cyclohexane group in the spacer arm.
