The invention relates to a method for jointly detecting sFlt-1 / PLGF and HLA-G for predicting pre-
eclampsia. The method comprises the following steps: collecting
serum specimen: respectively collecting5-10 ml of
venous blood from pregnant women in a pre-
eclampsia group and normal pregnant women with same
gestational weeks, centrifuging all specimens in a low temperature
centrifuge at 3000 rpm for10 min within 4 h, taking the serum and subpackaging in EP tubes, and storing in a refrigerator at minus 80 DEG C for testing;
coating: using a 0.05 M PH9.0
carbonate coated
buffer solution to diluteantibodies to the
protein content of 1-10[mu]g / ml, adding 0.1ml of the diluted antibodies into reaction holes of each
polystyrene board, staying overnight at 4 DEG C, discarding the solution in the holes the next day, and washing for 3 times; setting up standard holes and sample holes, washing, and setting up blank holes,
negative control holes and
positive control holes at the same time; adding
enzyme-labeled antibodies; adding 100 [mu]L of
horseradish peroxidase-labeled detection antibodies into each of the standard holes and the sample holes except for the blank holes, sealing the reactionholes with microplate sealers, and incubating in a water bath kettle or an
incubator at 37 DEG C for 60 min; performing board-washing; adding 50 [mu]L of a substrate A and a substrate B into each of the holes, and measuring OD values of each hole. The method is high in detection specificity and sensitivity.
