Any exposure to tobacco smoke during pregnancy is risky

...nd sometimes even direct exposure through maternal smoking ?or produced contradictory results. The original studies looked at mutation rates at the hprt gene located on the X chromosome in cord blood samples from newborns. Dr. Grant's analysis pooled the studies' data, looking for frequency of induced ...

...d to isolate RNA from the LCM sample shown in Figure 2. RNA from hprt was amplified from this sample by qRT-PCR (Figure 5A). In additi... Samples. (A) One-step qRT-PCR reaction to amplify hprt mRNA was performed with total RNA isolated from human ovary LCM sample ...

Housekeeping Genes: Universal Positive Controls in siRNA Knockdown Experiments

...y. Conclusion The housekeeping genes G6PDH and hprt can be used as a positive control for gene knockdown experiments when siRNA transfection conditions have to be optimized. The LightCycler Instru...

Quantification of siRNA Silencing Efficiency Using the LightCycler System

...ata from the housekeeping genes were used to normalize the GFP results (Figure 3). Of the five tested housekeeping genes (β2M, G6PDH, ALAS, hprt and PBGD) the expression level of β2Microglobulin (β2M) was closest to the expression level of GFP (Figure 3a). Therefore it was selecte...

High-Throughput Isolation of Total RNA

...cells was also subjected to molecular beacon RT-PCR analysis 5 using primers and a beacon specific for the low-abundance target hprt ( Figure 4 ). The beacon hybridizes quantitatively to the target sequence and emits fluorescence in this conformation. The thres...
