Genetic Tools from Gene Link

This application from Gene Link, Inc.for iPhone/iPod/iPad is geared towards life scientists, including college and graduate students for laboratory bench calculations and a quick short course in molecular genetics. Topics included are all related to nucleic acids research with an emphasis on utilizing properties that increase specific predetermined properties e.g duplex stability. The app also has advanced modules for setup of Polymerase Chain Reaction (PCR) and Quantitative Real Time PCR (Q-PCR).

The main focus of this app is to have a handy source of calculation modules and quick reference sections for designing and executing experiments involving PCR and Q-PCR. These techniques are routinely used in a molecular genetics laboratory for all type of research involving DNA. These vary from simple DNA amplification and confirmation to complex allele and genotyping for diagnostics. The application has sections to encourage users to design primer and probes using modified bases as substitutes for the natural four bases to enable specificity and increase nuclease resistance.

The application is divided into two sections; the Tools sections are an assortment of convenient calculators for the life scientist and the Reference section is for basic genetic information.
