    摘要： The apparatus comprises a movable member (10) which carries a plurality of cuvettes (11) containing material under test. Control means cause the member (10) to be moved to bring the cuvettes (11) successively into register with a photomultiplier (16), and in that position reagent is automatically added to a cuvette, giving rise to a luminescent reaction. Light from the reaction is detected by the photo-multiplier (16) and the resultant signal processed and recorded. The control means is triggered to stop the member (10), add reagent, record the signal from the luminescent reaction, and restart the member, from a photocell (28) which is illuminated through the member (10) only when a cuvette (11) is in register with the photomultiplier (16).According to the method, sample material containing the analyte for determination is mixed with a known amount or concentration of the same analyte labelled with a substance which is capable of taking part in a luminescent reaction. The mixture is then reacted with a known amount of another substance capable of reacting with the analyte and giving rise to a luminescent reaction with the labelling substance. From quantitative observation of the light from the luminescent reaction the amount or concentration of the analyte in the sample may be deduced.

    摘要： A dispensing device, for dispensing reagent into an array of reaction wells (16) in a photographic recording apparatus, comprises an array of tubes (28) which are mounted in a support (23). The support (23) contains a common chamber (29) into which the tops of all the tubes (28) open. The chamber (29) is connected with atmosphere via an opening (32) which is sealable manually to retain liquid in the tubes (28) when the latter are immersed in a reservoir (40) and which is unsealed to dispense the liquid. The recording apparatus has a housing (10) closable at the top by part of the support (23). A plate (11) having an array of holes (15) therethrough rests on a shutter (13) disposed above a photographic film holder (12). The plate (11) carries the reaction wells (16) in the holes (15).

    摘要： Assays, e.g. immunoassays, based on the chemiluminescent reaction between a peroxidase enzyme, e.g. horse radish peroxidase, a chemiluminescent 2,3-dihydro-1,4-phthalazinedione, e.g. luminol or isoluminol and an oxidant, e.g. hydrogen peroxide or a perborate, are improved by carrying out the reaction in the presence of a 6-hydroxybenzothiazole, especially 6-hydroxybenzothiazole itself or firefly luciferin. Light emission from the reaction is significantly enhanced by the 6-hydroxybenzothiazole.

    摘要： It has been a problem that the chemiluminescent emission produced by the peroxidase-catalyzed oxidation of a 2,3-dihydro-1,4-phthalazinedione is often weak or gives a poor signal-background ratio and therefore does not give the high degree of sensitivity required for assay purposes, particularly for assay of peroxidase used to label a reagent for example in ELISA. The present invention solves the problem by the finding the certain narrowly defined aromatic amines are enhancers of the reaction and accordingly provides for their use in an assay and kit. The amines are of general formula (I) ##STR1## wherein the R symbols (that is, R, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6) have any of the meanings (a) to (j) given below, all other R symbols in each meaning are hydrogen atoms and the fused rings are to be read in the same configurational sense as formula I:(a) R=R.sup.1 =CH.sub.3 ; R.sup.4 = ##STR2## (b) R.sup.4 = ##STR3## cyclohexyl, or alkyl or alkoxy having 1 to 4 carbon atoms (c) R.sup.2, R.sup.3 and R.sup.4 together represent the polycyclic fused ring system: ##STR4## (d) R.sup.3 and R.sup.4 together represent the fused ring or ring system ##STR5## (e) R.sup.3 and R.sup.4 together represent the fused ring system ##STR6## and R.sup.5 and R.sup.6 together represent the fused ring ##STR7## (f) R.sup.2 =NH.sub.2 and R.sup.4 = ##STR8## (g) R.sup.2 =R.sup.6 =CH.sub.3 and R.sup.4 = ##STR9## (h) R.sup.3 =C.sub.2 H.sub.5 (i) R.sup.2 =R.sup.4 =CH.sub.3 and(j) R.sup.3 =R.sup.4 =CH.sub.3.
