Praxilabs

OVERVIEW

-Gel Electrophoresis is a procedure used in molecular biology to separate and identify molecules (such as DNA, RNA) by size. The separation of these molecules is achieved by placing them in a gel made up of small pores and setting an electric field across the gel.

-The molecules will move based on their inherent electric charge (i.e., negatively charged molecules move away from the negative pole) and smaller molecules will move faster than larger molecules; thus, a size separation is achieved within the pool of molecules running through the gel. The gel works in a similar manner to a sieve separating particles by size; the electrophoresis works to move the particles, using their inherent electric charge, through the sieve.

Aim

  • Estimation of the size of DNA molecules.
  • Analysis of PCR products.

Techniques in Lab

  • Agarose Gel Electrophoresis of DNA fragments.
  • Visualizing DNA fragments using UV.

Tens of 3D simulations of science with you everywhere and all the time


You can easily access more than 130 of the 3D simulations of Physics, Chemistry and Biology anytime via your PC, laptop, tablet or even your smartphone, without any need to install an additional driver software.

Our virtual lab aims to facilitate the science teaching process for educators and also make it easy for students to absorb the theory and the application of all science experiments.

All of the 3D simulations are baked with a helping multimedia files to ensure that all learners can perform the science experiments without facing any difficulties.




Our virtual labs enable your institution to save most of physical labs budget


Save most of the money you always dedicate to spend on the materials and tools of the physical science labs. PraxiLabs will enable your students to repeat the steps of the experiments for unlimited times without any need to spend more money to get lab supplies.

Praxilabs will reduce the regular costs that allocated for the maintenance of the equipment of your physical labs as well as helps to increase its lifetime due to the lower frequency of usage.

You will also be able to teach your students how to perform the science experiments that requires a very expensive equipment without the need to purchase such equipment.
