Description of the drawings
Attached drawing 1 is standard fit curve
Specific implementation mode
The present invention is further described with reference to embodiments, but these embodiments not limit the scope of the present invention.
Embodiment 1:ELISA Plate is coated with and closing
20ugIL-6 monoclonal antibodies (the magnificent biology in Wuhan) are taken to be added to the carbonate buffer of 10ml0.05M pH values 9.6 It is uniformly mixed, is even added in 96 hole elisa Plates in liquid, per hole 100ul, 37 degree are reacted 1 hour, and 4 degree of coatings 16 of rear placement are small When, it pats dry, washing 3 times with conventional PBST washing lotions pats dry, and confining liquid is added, and reaction pats dry for 1 hour, 37 degree of air dry oven dryings 1 Hour, it is spare that 4 degree of refrigerators are placed in sealing.
Close formula of liquid:+ 0.2% polysorbas20 of 0.02MPBS+1%BSA+0.1%l caseins sodium salt.
Embodiment 2:HRP enzymes mark IL-6 monoclonal antibodies:
HRP enzymes are dissolved into ultra-pure water, its final concentration of 10mg/ml is made, 1ml is taken to take 500ml10mg/ml again, 4 degree anti- It answers 1 hour, adds 500ul1% ethylene glycol and be uniformly mixed, 4 degree are reacted 1 hour, take 250ul to be added in final product 5mgIL-6 monoclonal antibodies (the magnificent biology in Wuhan) are uniformly mixed, and are dialysed 16 hours in 0.05MPH9.6 carbonate buffer solutions, Midway change a not good liquor, add 30ul5mg/ml sodium borohydrides terminate reaction, 4 degree 2 hours, with G25 desalting columns centrifuge desalination obtain It is HRP-IL-6 enzyme markers to final product, 50% glycerine is added and places -20 degree preservations.
Developing solution is prepared:
A liquid:Sodium acetate 12.6g+ citric acid 1.6g+ urea peroxides 0.3g is settled to 500ml;
B liquid:EDTA-2Na0.2g+ citric acids 0.95g+50ml glycerine+tetramethyl biphenyl diamines 0.2g (is dissolved in 1mlDMSO In) it is settled to 500ml.
Standard items are prepared:After IL-6 antigens chemiluminescence assignment, it is diluted to 640pg/ml (1ml) with enzyme dilution and does Initial concentration.
Standard dilutions:+ 0.2% Triton X-100+0.1%proclin300 of 0.02MPBS+10% calf serums.
Embodiment 3:The determination of enzyme dilution optimal use concentration
Enzyme dilution formula:+ 0.2% Triton X-100+0.1%proclin300 of 0.02MPBS+10% calf serums.
The determination of best HRP-IL-6:
Product in embodiment 2 is diluted to 1 respectively with enzyme dilution is dilute:1000,1:2000,1:4000,1:8000;
IL-6 antigens are diluted to 20pg/ml, 1000pg/ml with enzyme dilution, make upper negative control respectively of dilution And parallel hole is done, take 50ul that 1 ready-made production board of embodiment is added, then be respectively separately added into HRP-IL-61:1000,1:2000, 1:4000,1:8000, each 50ul, 37 degree are reacted 30 minutes, and washing 4 times with conventional PBST washing lotions pats dry addition TMB developing solution (routines Kit) be protected from light colour developing 15 minutes after be added terminate liquid (2M sulfuric acid) terminate.It is read respectively with 450nm wavelength microplate reader.
As a result as follows:
As a result illustrate, 1:The OD values of 2000 enzymes are bigger, and background is relatively low so enzyme optimal use a concentration of 1:2000.
