页面 2 - Gene Expression Profiling

Cell-based assays are widely used in basic and translational research as cost-effective and accessible models to mimic in vivo responses. To obtain reliable data, assessing the health of cultured cells prior to any assays is essential. Furthermore, many cell-based assays require quantification of cell

In this final installment on how to improve your qPCR gene expression profiling (see 6 Tips to Improve qPCR: part 1 and part 2 for previous discussion), we will discuss pipetting tips and the benefits of a separate reverse transcription step in qPCR template preparation.

Tip #5. Good Laboratory Practice

After watching displays of astounding athletic prowess in the 2016 Olympics, I was inspired to take a closer look at the science behind exercise training, recovery, and injury with a focus on the importance of blood vessels during exercise.

Let’s start with some basic training: Why are blood vessels

Despite being essential for any experiment involving DNA replication, people rarely give primers a second thought.  To coincide with the launch of our new qPCR gene reference tool, we’ll be giving them a little more of the praise they deserve.

In this next installment on how to improve your qPCR gene profiling (see 6 Tips to Improve qPCR for previous discussion), we would like to discuss the limitations of melting curve analysis and PCR inhibitors.

Tip #3. Melting curve analysis is NOT sufficient for assessing qPCR product specificity.

Gene expression analysis is critical for understanding the transcriptome profiles of primary cells and how they directly influence the cells’ functionality. In addition, the transcriptome profile can affect cell proliferation, differentiation, senescence, or apoptosis. Traditional reporter-gene assays

qPCR array provides a quick, powerful and sensitive approach for gene expression profiling. To help our customers acquire accurate and consistent results, we are happy to share some tips for better qPCR.

Tip #1. Good primer design is the key to a successful qPCR array.

The success of a qPCR array depends

Dye-based qPCR assays, such as SYBR® Green and EvaGreen®, have many advantages over probe-based qPCR assays. Dye-based systems are desirable because they are highly adaptable, cost effective, and time efficient. qPCR specificity, however, is a vital factor to consider when using dye-based qPCR assays.
