 · Silica gel, also known as silicic acid gel or silica gel, has the chemical formula mSiO2·nH2O, a white transparent solid substance. It is an amorphous form. Silica gel is a highly active, porous material with a large internal surface area and an internal surface area of more than 450 m2 per g of silica gel. Therefore, it has a strong adsorption property to …

 · Silica gel can be used to maintain a specific relative humidity level (e.g., a low level as a desiccant) or to maintain an RH range (e.g., levels between 40 to 60% RH). Before use, the gel must be conditioned to the desired RH. The effectiveness of the silica gel also depends on: a tightly-sealed exhibit case, with little or no air leakage to ...

 · Experiments showed that (nano)silica derivatized with N -methoxypolynitroanilines may act as a sensitive material for arginine and lysine, turning its color from yellow to blue. Other amino-acids such as glycine, valine, cysteine, cystine, alanine, histidine and phenylalanine do not show this behavior. Experimental

Arginine is effective in suppressing aggregation of proteins and may be beneficial to be included during purification processes. We have shown that arginine reduces non-specific protein binding in gel permeation chromatography and facilitates elution of antibodies from Protein-A columns. Here we hav …
