Andrew Hessel is a Seer…Personalized Medicine is Very Near

 :: Posted by American Biotechnologist on 01-05-2010

Ever heard of open source computing? What does that have to do with drug discovery and molecular bioiolgy? Andrew Hessel of the pink army collective thinks that lessons learned from open source computing can be used in “open-source biology” which will eventually lead to faster drug discovery and an economically viable model for personalized medicine.

Check out the video. It is facinating.

Bio-Rad Reprint: Mutational Analysis of the ATM Gene in Familial Breast Cancer Using iProof High-Fidelity DNA Polymerase

 :: Posted by American Biotechnologist on 12-30-2009

Breast Cancer is the most common cancer among women in the developed world. In 5-10% of the cases it is thought to be heritable. Two highly penetrant breast cancer genes have been identified. However, a large number of cases with familial predispositon to breast cancer cannot be explained by mutations in these two genes.

See the following article to learn how iProof polymerase significantly reduced PCR cycling time and successfully and reliably amplified sequencing quality DNA fragments that had failed repeatedly using previous methods.

Great Tool for 2D PAGE Users

 :: Posted by American Biotechnologist on 12-25-2009

If you are actively involved in 2D experiments you must check out the 2D Doctor. It is a great tool for troubleshooting 2D experiments which can often be filled with anguish (aka streaking) and frustration (yucky gels). The tool shows you pictures of typical gels and asks you to click on the one that looks most like yours. It then gives suggestions on how to troubleshoot your experiment. If you are still stumped, there is a database of 2D-Doctor references and how to videos. And as a final (or maybe a first) resort you can click on the ask the 2D expert button to leave a detailed message for a Bio-Rad scientist who will get back to you.

Yes…2D is frustrating but it can also be very rewarding. It allows you to get tons of information from just a few experiments. Don’t despair! Help is available.

Are you using the right reference genes?

Considering Real-Time PCR for gene expression analysis. Have you tested multiple reference genes or are you just going to run with your favorite such ast 18S? Check out this important article before you move forward. It could save you lots of grief in the long run.

Suitable reference genes for real-time PCR in human HBV-related hepatocellular carcinoma with different clinical prognoses
Li-Yun Fu et al. BMC Cancer 2009, 9:49

Housekeeping genes are routinely used as endogenous references to account for experimental differences in gene expression assays. However, recent reports show that they could be de-regulated in different diseases, model animals, or even under varied experimental conditions, which may lead to unreliable results and consequently misinterpretations. This study focused on the selection of suitable reference genes for quantitative PCR in human hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) with different clinical outcomes.
