Transformation-associated recombination cloning (TAR)

Transformation-associated recombination (TAR) cloning in yeast is a technique to selectively isolate a gene sequence without the construction of a genomic library. It involves the recombination between the two ‘hooks’ of the TAR vector and the flanking sequence of the targeted gene. Application of TAR cloning includes the analysis of the disease causing genome of [...]

Monoclonal antibodies from hybridoma

Monoclonal antibodies (mAbs) was considered to have the potential to be the golden ‘bullet’ in human therapeutics. The term magic ‘bullet’ concept was coined by the Nobel Prize lorret and it describes that if a compound that can seek out and target a disease organism, than a toxin can be delivered. These are called conjugated [...]

Tumor-Killing Bacteria

Imagine a bacterium that, when injected into the bloodstream, would travel to the site of a tumor, insert itself into the cancer cell, and then produce a cancer-killing compound. That’s exactly what scientists at the University of California, Berkeley (UCB) and University of California, San Francisco (UCSF) have set out to do. Traditional cancer therapies [...]

Bacteria have their own immune system protecting against outside DNA

Bacteria like Salmonella have a complicated immune system that helps them recognize and isolate foreign DNA trying to invade their cell membrane, according to a University of Washington-led study in the June 8 issue of Science Express.read more | digg story

Cipro,Tamiflu, potassium iodine. The new 1st aid kit for the 21th century?

Cipro for anthrax, Tamiflu for Avian influenza, and potassium iodine for radiation poisoning??? But how effective would this be? For example, once exposed to the bird flu you have 48hrs to take Tamiflu to be most effective. Most people would not know when they have exposed to the virus. One way to get around this [...]
