Development of ELISA based detection system for lethal toxin of Clostridium sordellii.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND &
objectivesClostridium sordellii and its toxins are associated with diseases in animals as well as human. C. sordellii produces two protein toxins (lethal toxin and haemorrhagic toxin). Lethal toxin has gained more importance due its high toxicity. The present study was carried out to develop a sandwich ELISA for detection of lethal toxin of C. sordellii.
methodsThe catalytic domain (1.6 kb) of lethal toxin of C. sordellii was PCR amplified, cloned into pQE30 UA vector and transformed into Escherichia coli SG 13009. Expression conditions were optimized and the recombinant protein was purified under native condition using Ni-NTA affinity chromatography, confirmed by SDS-PAGE and Western blot. Antibody was generated against the purified recombinant protein using Freund's complete and incomplete adjuvants (FCA and FIA) in BALB/c mice and rabbit. A sandwich ELISA was optimized for the detection of lethal toxin.
resultsThe maximum recombinant protein expression was achieved at 0.5 mM IPTG (isopropylthiogalactoside) induction 4.0 h of post-induction. The polyclonal antibody raised in mice and rabbit showed a titre up to 1:512000. The produced antibody was highly sensitive with the detection limit of 0.3 ng/ml of lethal toxin at 1:4000 dilutions of mice (capturing) and rabbit (revealing) antibody. INTERPRETATION &
conclusionsAn ELISA based detection system was developed for the detection of lethal toxin of C. sordellii. The developed detection system was found to be specific as there was no cross-reactivity with any other clostridial toxins. It will be useful for the detection of lethal toxin of C. sordellii in clinical and environmental samples.
