blue cuprammonium complex that is formed when copper(II) ions are added to PEI [2‚3]. This complex has a strong absorbance peak at 285 nm and a weaker one at 630 nm. Unfortunately‚ the absorption maximum at 285 nm is close to that of DNA (260 nm). In addition‚ most cell culture media contain components that absorb at this wavelength. At 630 nm‚ there is much less interference from biological molecules‚ but the signal from the cuprammonium complex is also low. We successfully adapted a commercially

Civil aviation came about after World War one when pioneers explored new uses for aircraft‚ before that aircraft were only used for war purposes. In 1908 the British army developed aircraft‚ a few years before in 1904 J. E. Cooper‚ from the British war office‚ visited the Wright Brothers. His aim was to bring back information and skills on aircraft. This did not happen because the Wright brothers asked for $100‚000 for the method of aircraft and a further $100‚000 for the formulae and theoretical

The human body has eleven main body systems. They are groups of bodily organs coming together to keep the human body going; they can perform one or more functions. The eleven body systems consist of the skeletal system‚ muscular system‚ nervous system‚ circulatory system‚ immune system‚ endocrine system‚ digestive system‚ excretory system‚ respiratory system‚ integumentary system‚ and the reproductive system.

The experiment was separated into four stages‚ the first being preparation of cell competency. In this stage two vials were placed in ice baths‚ one vial containing 50 µL of E. coli and the other containing a CaCl2 solution. 630 µL of the CaCl2 solution was then transferred to the E. coli vial‚ using a sterile pipet. After tapping the tube to mix the solution‚ it was then returned to the ice bath to continue incubation for at least 10 minutes. The cell competency preparation was carried out by the
