- 摘要:
- 以大肠杆菌和农杆菌(含有几丁质酶基因)为试材,研究了菌液浓度对PCR扩增的影响。结果表明:当菌液OD值达到0.006后作为模板进行PCR扩增,经电泳检测即可出现条带,随着OD值的增加电泳条带逐渐变亮;OD值在0.200~0.700的电泳条带比较清晰;LB液体培养基中的成分对DNA模板没有影响,菌液DNA能正常扩增。
- Abstract:
- Taking Escherichia coli and Agrobacterium were studied,in which included Chitinase gene as materials the effect of bacterial concentration on Polymerase chain reaction.The results showed that the band would appear when the bacterial OD value increased to 0.006 and then took it as the template for PCR by electrophoresis,meanwhile,the electrophoresis bands became more and more brighter with increasing of the OD value;When the OD value was between 0.200 to 0.700;The electrophoresis bands were quiet clear;The ingredients in the liquid of LB medium failed to effect on DNA template,and the bacterial DNA could be amplified as normal as usual.
