（1）DETERMINATION NOTES BEFORE THE EXPERIMENT
1）Rise the temperature of all kit and the need to room temperature before using(20-25 ℃).
2）Put back all reagent 2-8 ℃immediately after use.
3）The analysis of ELISA reproducibility depends largely on the consistency of the washing board,
the correct operation of washing board is the point in the determination program of ELISA.
4）During all thermostatic incubation process, it should avoid light irradiation, cover plate with
sealed microporous membrane.
1）Removed reagents from refrigeration environment, bring them to room temperature (20-25 ℃)
balance 30min above, note each liquid reagent is required to shake well before use.
2）Remove the required number of microporous board, put back unneeded microporous into
self-appointed bag, and keep in 2-8 ℃.
3）Washing liquid also needs to room temperature before use.
4）Numbering: numbering the sample and standard substance corresponding microporous the
sequential Numbers, each sample and standard parallel make 2 holes and record the standard holes
and sample hole position.
5）Adding standard /sample: add 50ml standard/samples to corresponding microporous, then add
the antibody working liquid 50ml/hole, gently oscillation blending, and cover with membrane
rearmounted at 25 ℃ avoiding light environment to react 30min.
6）Washing board: carefully open the liquid membrane, dry the hole, fully washing 4-5 times with
scouring working liquid (see with liquid 1) 250ml/hole, , each time interval 10s, pat dry with an
absorbent (after pat dry, pierce the unclear bubble with unused spear).
7）Add HRP secondary antibody: Add HRP secondary antibody100ml/hole, gently oscillation
blending, and cover with cover membrane at 25 ℃ avoiding light environment reaction 30min,
repeat washing board of step 6.
8）Show color: join substrate liquid A liquid 50ml/hole, add substrate liquid B liquid 50ml/hole,
gently oscillation blending, and cover with membrane rearmounted at 25 ℃ avoiding light
environment and let react 15min (see note 8).
9）Determination: join terminated liquid 50 ml/hole, gently oscillation blending, and set microplate
in 450nm place (suggest using dual wavelength 450/630nm to detect, please finish reading data in
5min), detect OD value of each hole. (if there is no terminated liquid, it can undertake judging by
Result determination have two kinds of methods, roughly judgement usable 1 method, and quantitative determination by the first two methods. Note sample absorb light value and ampicillin penicillin content of a negative correlation.
1.Using the sample of average absorbance of the value and the standard comparison can obtain its concentration range (PPB). Hypothesis sample 1 absorbance of the value of 0.190, sample 2 absorbance of the value of 0.742, standard fluid absorbency value is respectively: for 0ppb 1.802; For 1.428; PPB 0.2 - For 1.011 0.6 PPB, For 0.560; 1.8 PPB For 0.257; PPB 5.4, 16.2 PPB for 0.110. Then sample 1 concentration range is 5.4 PPB - 16.2 PPB multiplying by the corresponding diluted times can draw in their sample ampicillin penicillin residual concentration range, Sample 2 concentration range is 0.6 PPB - 1.8 PPB multiplying by the corresponding diluted times can draw in their sample ampicillin penicillin residual concentration range.
