Iron (Fe)
Iron is a relatively abundant metal found in the sun and other stars and in meteorites. It is the fourth most abundant element in the earth's crust by weight.
Pure iron is very reactive and rapidly corrodes. It has four allotropic forms or ferrites; the alpha form is magnetic, but the magnetism disappears in the beta form. Iron is hard, brittle, fairly fusible and used to produce steel and other alloys. Common iron consists of four isotopes, and ten other isotopes are known to exist.
Iron is vital to the functions of plants and animals and carries oxygen in hemoglobin.

Alkali Scientific Proteinase K, 50 Milligrams
Proteinase K is a broad-spectrum serine protease widely used in molecular biology for the digestion of proteins and removal of enzymatic contaminants. It is particularly effective in breaking down proteins during DNA and RNA extraction procedures, ensuring high purity of nucleic acids. The enzyme remains active under a wide range of temperatures and pH conditions and is capable of digesting proteins even in the presence of detergents and denaturing agents. Proteinase K is commonly used to inactivate nucleases, degrade structural proteins, and improve yield during sample preparation. It is an essential reagent in genomics, forensic analysis, and diagnostic workflows requiring efficient protein removal.
Alkali Scientific D (+) Galactose, 500 G
D (+) Galactose, 500 G, is a high-quality reagent used in a variety of scientific and medical applications. This pure D-form galactose is crucial for studies on carbohydrate metabolism, particularly in relation to the enzymes involved in galactose processing. It is frequently used in the preparation of culture media, as it serves as an energy source for certain bacteria and yeast. Galactose is also critical in glycobiology research, particularly for experiments related to glycosylation and the modification of proteins and lipids. The 500g package size is ideal for medium to large-scale laboratory experiments and commercial production of galactose-based formulations.
