What's the difference between chromogen and chromogenic?
Chromogen
Definition:
() Vegetable coloring matter other than green; chromule.
() Any colored compound, supposed to contain one or more chromophores.
Example Sentences:

(3) It has now achieved wide applicability to the measurement of cellular biochemical activity by means of stoichiometric chromogenic reactions.
(4) The turnover of fluorogenic substrates is lower for all enzymes than the turnover of chromogenic substrates but due to the more sensitive detection of fluorogenic products the detection limits for all conjugates were lowered too--especially for beta Gal-IgG by a factor of 333 compared to the colorimetric procedure.
(5) Methods based on the application of chromogenic and fluorogenic substrates enable specific and rapid detection of a variety of bacterial enzymatic activities.
(6) Fluorogenic 6-octanoyl- and 6-hexadecanoyl-amino-4-methylumbelliferyl beta-D-glucopyranoside were much less readily hydrolyzed by both human and animal glucocerebrosidase than chromogenic 2-hexadecanoylamino-4-nitrophenyl beta-D-glucopyranoside.
(7) Diethyldithiocarbamate did not influence the effects of NiCl2 on TBA-chromogens in liver homogenates or on serum AST and ALT activities but acted synergistically with NiCl2 to diminish serum alkaline phosphatase activity and to increase serum bilirubin concentration.
(8) The newly developed endotoxin specific chromogenic Limulus assay (endospecy test), which is devoid of factor G, did not react with any rabbit serum.
(9) Substratum-bound enzyme could be solubilized in buffers containing sodium dodecyl sulfate (SDS) or Triton X-100 and demonstrated by zymography following electrophoresis or assayed for amidolytic activity with a chromogenic substrate (Kabi S-2251).
(10) The released glycerol is oxidized with glycerol dehydrogenase from Erwinia aroideae in the presence of NAD+, were the reduction of the enzyme-linked NAD+ is coupled to the reduction of nitro blue tetrazolium as a chromogenic indicator with phenazine methosulfate serving as an intermediate electron carrier of NADH.
(11) The chromogenic substrate, CPRG (chlorophenol red-beta-D-galactopyranoside), was compared with ONPG (o-nitrophenyl-beta-D-galactopyranoside) by kinetic analysis with purified beta-galactosidase.
(12) Using peptide 4-methoxy-2-naphthylamide substrates (Bz-Arg-MNA, Z-Lys-Arg-MNA, Z-Gly-Arg-MNA, Z-Pro-Arg-MNA and Z-Gly-Pro-Arg-MNA) and Fast Garnet GBC as chromogen the red azo dye was found to precipitate in the cytoplasmic granules of the cutaneous mast cells.
(13) The continuous chromogenic tissue factor assay has been compared to one-stage and two-stage coagulation assays, and its sensitivity has been established using purified human placental tissue factor.
(14) Cleavage of chromogenic peptidyl substrate by TFA165A166.VIIa complexes was not diminished, demonstrating that TFA165A166 supported enhancement of catalytic function of the VIIa protease domain.
(15) Factor X-activating activity (FXAA) was determined by a chromogenic assay in normal and malignant breast tissue.
(16) Diaminobenzidine and tetramethylbenzidine were used as chromogens to distinguish ChAT (protein) and VIP (peptide) immunoreactivities.
(17) In an enzyme immunoassay for anti-Salmonella antibodies using glucose oxidase as the indicator enzyme, the molybdate-enhanced polyvinyl alcohol- and starch-glucose-iodide substrate systems were as sensitive as a conventional glucose oxidase assay system employing horseradish peroxidase as a secondary enzyme and a suitable hydrogen-donating chromogen.
(18) strain 3707, a chromogenic rapid grower; C72 to C78 (av.
(19) 4. alpha-D-mannosidase was the most active with both fluorescent and chromogenic substrates.
(20) A sample containing fibrin is incubated with t-PA, plasminogen and a plasmin-sensitive chromogenic substrate.
