or convey a positive charge onto the DNA or RNA cells. These positively charged nucleic acids are attracted to negatively charged cell membranes. Examples of chemical transfection include calcium phosphate prec
There are three types of complexes: (i) Cationic complexes: These are the complexes in which the complex ion carries a net positive charge. Example: [Ni(NH3)6]^(2+),[Cr(NH3)6]^(3+) etc, (ii) (ii) Anionic complexes: These are the complexes in which the c
What is Chemical Synthesis? Chemical synthesis describes the physico-chemical transformation that occurs when two or more simpler molecules combine in a controlled fashion to produce a more complex chemical product. Often chemical synthesis is far more complex than A+B = C, and mixtures can occur ...
This can be achieved with compounds like calcium phosphate, polycations, and liposomes or more current technologies such as cationic lipids, polymers, dendrimers, and nanoparticles. Using calcium phosphate for delivery is the oldest and least expensive way to introduce nucleic acids into cells. This ...
Taking a simple example from biochemistry, the conformational and property space of even a short peptide is considerably greater than that of its constituting amino acids =-=[37]-=-. But what this description of complexity misses are the structural and dynamic dimensions of complex systems. Th...
Likecationic surfactants, these undergo inactivation when mixed with anionic detergents and complex anions such as phosphate,carbonate, and silicate. Solution Form Chlorhexidine digluconate solution is a bis(biguanide) family cationic broad spectrum antibiotic that is available in a range of concentrations ...
What is Chemical Reaction Kinetics? Chemical reaction kinetics provide a quantitative or qualitative measurement of the rate(s) of reactions and provide insight into the dependence of these rates on variables such as concentration, temperature, pressure, the presence of catalysts, the physical state of...
It has been shown that in vivo mitochondrial ATP production is improved in older adult skeletal muscle after a single dose of elamipretide in a randomized trial[83]. Elamipretide, an aromatic, cationic tetrapeptide, works by localizing to the inner membrane, where it binds to cardiolipin to ...
Like the cationic, the anionic resin is also made from styrene, but contains positively charged quaternary ammonium groups, and will be pre-charged with hydroxide ions. This resin will attract the negatively charged ions (HCO3-, Cl-, SO4--, etc.) and releases an equivalent amount of hydroxide...
