目的:分析不同浓度的抗凝剂EDTA-Na2对家禽血液指标及基因组DNA抽提的影响。方法:采集鸡血,分别加入0.6(A组)、0.9(B组)、1.2(C组)、1.5(D组)、1.8(E组)和2.1(F组) mg/mL的EDTA-Na2,立即检测白细胞总数(WBC)、淋巴细胞(LYM)、中间细胞(MID)、粒细胞(GRAN)、红细胞总数(RBC)、血红蛋白(HGB)、血红蛋白含量(MCH)和血小板总数(PLT),用SPSS软件分析检测数据;用酚-氯仿法提取添加不同量抗凝剂的血液基因组DNA,并进行PCR扩增,基因组DNA和PCR产物用琼脂糖凝胶电泳检测。结果:A组样品出现肉眼可见的凝块,B组有2/7样品有凝集现象,C、D、E和F组均无凝集现象。A组凝集现象严重无法进行血液指标测定,其余5组样品中,对于RBC和HGB指标,C组与B组相比无显著性差异,与D、E、F组差异极显著(P<0.01);对于PLT,C组与B组相比无显著性差异,与D、E、F组差异显著(P<0.05);WBC无显著变化。除A组外,各组均能获得质量较好的基因组DNA,并能扩增出目的条带。结论:除A组外,不同浓度的EDTA-Na2对基因组DNA提取和PCR扩增无影响。以EDTA-Na2作为禽血抗凝剂时,建议用量应不低于1.2 mg/mL。

Objective: To analyze the effect of different concentrations of EDTA-Na2 on the poultry blood indexes and genomic DNA extraction. Methods: One milliliter blood were collected from chicken wing vein, 0.6(A), 0.9 (B), 1.2(C), 1.5(D), 1.8(E) and 2.1(F) mg/mL EDTA-Na2 anticoagulants were added to each group, respective?ly. Each group consisted of 7 samples. WBC, LYM, MID, GRAN, RBC, HGB, MCH and PLT were measured for each sample. The data were analyzed using SPSS. Genomic DNA was extracted with phenol-chloroform method from each sample and used for PCR to amplify β-actin. DNA and PCR products were analyzed by agarose gel electrophoresis. Results: All samples in group A appear clots, 2/7 of group B samples appear clots, and the re?maining four groups did not appear clots. We couldn't test blood indexes of group A because of agglutinate phe?nomenon. The RBC and HGB did not differ between group C and group B, but there were significant differences (P<0.01) when compared with group D, E, F. The PLT had the same trend(P<0.05) as the RBC and HGB. There were no significant differences among all groups for WBC. Genomic DNA was good enough to used for PCR amplification except for group A. Conclusion: Different concentrations EDTA-Na2 have no significant effect on genomic DNA quality and PCR amplification except group A. The suggested dosage should be not less than 1.2 mg/mL when using EDTA-Na2 as anticoagulant in poultry.
