一般的sp法步骤啊,具体如下:
1、烤片,68℃,20分钟,
2、常规二甲苯脱蜡,梯度酒精脱水;二甲苯I20min?二甲苯II20min?100%酒精10min?100%酒精10min?95%酒精5min?80%酒精5min?70%酒精5min
3、阻断灭活内源性过氧化物酶:3%H2O237℃孵育10min,PBS冲洗3X5min;
4、抗原修复:置0.01M枸橼酸缓冲液(PH6.0)中用煮沸(95℃,15-20min),自然冷却20min以上,再用冷水冲洗缸子,加快冷却至室温,PBS冲洗3X5min。
5、正常羊血清工作液封闭,37℃10min,倾去勿洗。
6、滴加一抗4℃冰箱孵育过夜,PBS冲洗3X5min(用PBS缓冲液代替一抗作阴性对照);
7、滴加生物素标记二抗,37℃孵育30min,PBS冲洗3X5min;
8、滴加辣根过氧化物酶标记的链霉素卵白素工作液,37℃孵育30min,PBS冲洗3X5min;
9、DAB/H2O2反应染色,自来水充分冲洗后,苏木素复染,常规脱水,透明,干燥,封片。
General sp method steps ah, as follows:
1, baked slices, 68 ℃, 20 minutes,
2, normal xylene dewaxing, gradient alcohol dehydration; xylene I20min xylene II20min 100% alcohol 10min 100% alcohol 10min 95% alcohol 5min 80% alcohol 5min 70% alcohol 5min
3, block the inactivation of endogenous peroxidase: 3% H2O237 ℃ 10min incubation, PBS wash 3X5min;
4. Antigen Recover: Set 0.01M citrate buffer (PH6.0) with boiling (95 ℃, 15-20min) for more than 20min, then rinse the cylinder with cold water, cool to room temperature and rinse with PBS for 3X5min.
5, normal sheep serum working fluid closed, 37 ℃ 10min, do not dump.
6, dropping the first antibody incubated overnight at 4 ℃ refrigerator, PBS wash 3X5min (PBS buffer instead of primary antibody as a negative control);
7, dropping biotin labeled secondary antibody, 37 ℃ incubated 30min, PBS wash 3X5min;
8, dropping horseradish peroxidase labeled streptomycin avidin working solution, incubated at 37 ℃ 30min, PBS washed 3X5min;
9, DAB / H2O2 reaction staining, tap water fully washed, hematoxylin counterstain, conventional dehydration, transparent, dry, sealing pieces.
