  1. 结果分析

定量实验至少需要三个生物学重复。反应结束后需要确认扩增曲线及熔解曲线。

1) 扩增曲线:标准扩增曲线为S型。

Ct值落在20-30之间时,定量分析最准确;

Ct值小于10,需要将稀释模板后,重新进行实验;

Ct值介于30-35之间时,需要提高模板浓度,或者增大反应体系的体积,以提高扩增效率,保证结果分析的准确性;

Ct值大于35时,检测结果无法定量分析基因的表达量,但可用于定性分析。

2) 熔解曲线:

熔解曲线单峰,表明反应特异性好可以进行定量结果分析;若熔解曲线出现双峰或者多峰,则不能进行定量分析。

熔解曲线出现双峰,需要通过DNA琼脂糖凝胶电泳判断非目标峰是引物二聚体还是非特异性扩增。

如果是引物二聚体,建议降低引物浓度,或者重新设计扩增效率高的引物。

如果是非特异性扩增,请提高退火温度,或者重新设计更高特异性的引物。

  1. 引物设计指南

1)推荐引物长度25 bp左右。扩增产物长度150 bp为佳,可以在100 bp-300 bp内选择。

2)正向引物和反向引物的Tm值相差不宜超过2℃。引物Tm值60℃-65℃为佳。

3)引物碱基分布要均匀,避免出现连续的4个相同碱基,GC含量控制在50%左右。3’端最后一个碱基最好为G或C。

4)引物内部或者正反两条引物间最好避免出现有3个碱基以上的互补序列。

5)引物特异性需要用NCBI BLAST程序进行核对。避免引物3’端有2个碱基以上的非特异性互补。

6)设计完成的引物需要进行扩增效率的检测,只有具备相同扩增效率的引物才可用于定量比较分析。

Q建议qPCR 实验用几步法?

A常用 2 步法。需提高扩增特异性,可选用 2 步法或提高退火温度。在扩增效率低, ct 值过大的时候,可以改用 3 步法或延长延伸时间。

Q预变性 5 min 调整成了 10min,对于实验结果有影响吗?

A:有影响,预变性时间较长可能会影响酶的活性,导致 PCR 产物的产量有所降低。

QqPCR 实验结果的有效性?为什么建议Ct 值要大于 15?

A有效性要满足三个条件1标准曲线扩增效率范围:90110%,对应斜率为  33.5 R2>0.98 (扩增效率=10-1/斜率1),当斜率=-3.32 时,扩增效率=100%。2)扩 增曲线S 型曲线,且 Ct 值在 15-35 之间,阴性对照 Ct>35 或无 Ct 值。3)熔解曲线为单一峰。

Ct 值大于 15 个循环是因为 3-15 个循环的荧光值标准差的 10 倍是荧光阈值,Ct 值太小了会影响曲线。

Q同一基因复孔间熔解曲线 Tm 值有差异?

A:同样的扩增产物也会出现Tm 值有微小差异,一般差异在 1 度以内都可以接受。

Q为什么稀释了模板CT 值反而变小了?

A:一般 CT 值与模板起始浓度呈负相关,浓度越高,CT 值越小。但也有很多特殊情况, 比如体系中存在抑制物或是模板不纯,这时候稀释模板反而能使 CT 值变低。

Q内参CT 值小于 20,目的基因均大于 30,怎么办?

A:可能是目的基因为低丰度表达基因导致。建议a)换用内参;b)换引物;c)换检测线性范围更广的qPCR mix。

  1. 结果分析

定量实验至少需要三个生物学重复。反应结束后需要确认扩增曲线及熔解曲线。

1) 扩增曲线:标准扩增曲线为S型。

Ct值落在20-30之间时,定量分析最准确;

Ct值小于10,需要将稀释模板后,重新进行实验;

Ct值介于30-35之间时,需要提高模板浓度,或者增大反应体系的体积,以提高扩增效率,保证结果分析的准确性;

Ct值大于35时,检测结果无法定量分析基因的表达量,但可用于定性分析。

2) 熔解曲线:

熔解曲线单峰,表明反应特异性好可以进行定量结果分析;若熔解曲线出现双峰或者多峰,则不能进行定量分析。

熔解曲线出现双峰,需要通过DNA琼脂糖凝胶电泳判断非目标峰是引物二聚体还是非特异性扩增。

如果是引物二聚体,建议降低引物浓度,或者重新设计扩增效率高的引物。

如果是非特异性扩增,请提高退火温度,或者重新设计更高特异性的引物。

  1. 引物设计指南

1)推荐引物长度25 bp左右。扩增产物长度150 bp为佳,可以在100 bp-300 bp内选择。

2)正向引物和反向引物的Tm值相差不宜超过2℃。引物Tm值60℃-65℃为佳。

3)引物碱基分布要均匀,避免出现连续的4个相同碱基,GC含量控制在50%左右。3’端最后一个碱基最好为G或C。

4)引物内部或者正反两条引物间最好避免出现有3个碱基以上的互补序列。

5)引物特异性需要用NCBI BLAST程序进行核对。避免引物3’端有2个碱基以上的非特异性互补。

6)设计完成的引物需要进行扩增效率的检测,只有具备相同扩增效率的引物才可用于定量比较分析。

Q建议qPCR 实验用几步法?

A常用 2 步法。需提高扩增特异性,可选用 2 步法或提高退火温度。在扩增效率低, ct 值过大的时候,可以改用 3 步法或延长延伸时间。

Q预变性 5 min 调整成了 10min,对于实验结果有影响吗?

A:有影响,预变性时间较长可能会影响酶的活性,导致 PCR 产物的产量有所降低。

QqPCR 实验结果的有效性?为什么建议Ct 值要大于 15?

A有效性要满足三个条件1标准曲线扩增效率范围:90110%,对应斜率为  33.5 R2>0.98 (扩增效率=10-1/斜率1),当斜率=-3.32 时,扩增效率=100%。2)扩 增曲线S 型曲线,且 Ct 值在 15-35 之间,阴性对照 Ct>35 或无 Ct 值。3)熔解曲线为单一峰。

Ct 值大于 15 个循环是因为 3-15 个循环的荧光值标准差的 10 倍是荧光阈值,Ct 值太小了会影响曲线。

Q同一基因复孔间熔解曲线 Tm 值有差异?

A:同样的扩增产物也会出现Tm 值有微小差异,一般差异在 1 度以内都可以接受。

Q为什么稀释了模板CT 值反而变小了?

A:一般 CT 值与模板起始浓度呈负相关,浓度越高,CT 值越小。但也有很多特殊情况, 比如体系中存在抑制物或是模板不纯,这时候稀释模板反而能使 CT 值变低。

Q内参CT 值小于 20,目的基因均大于 30,怎么办?

A:可能是目的基因为低丰度表达基因导致。建议a)换用内参;b)换引物;c)换检测线性范围更广的qPCR mix。
