* Approximate absorption (Abs) and fluorescence emission (Em) maxima for conjugates, in nm. ** Reactive Dye or Biotin has the succinimidyl ester (SE, NHS ester) group unless noted otherwise. § Human vision is insensitive to light beyond ~650 nm, and therefore it is not possible to view the far-red– and near-infrared–fluorescent dyes by looking through the eyepiece of a conventional fluorescence microscope. NA = Not applicable.

(Ab) = Antibody Labeling Kit
(APEX) = APEX™ Antibody Labeling Kit.
(ARES) = ARES™ DNA Labeling Kit.

(R IgG) = Zenon Rabbit IgG Labeling Kit.
(S) = Sulfosuccinimidyl ester
(SAIVI) = SAIVI™ Antibody Labeling Kit.
(SDP) = Sulfodichlorophenol ester.
(STP) =  Sulfotetrafluorophenol ester
(TFP) = Tetrafluorophenyl ester.
(TSA) = Enhanced with TSA™ technology.
(ULYSIS) = ULYSIS Nucleic Acid Labeling Kit.
(X) = An aminohexanoyl spacer between the dye and the SE.

(XX) = Two aminohexanoyl linkers conjugated to provide a 14-atom spacer between the dye and SE.
