Bio-Rex 70 is a selective adsorbent resin produced by Bio-Rad Laboratories, primarily used in the separation and purification of biomolecules, such as proteins, peptides, and nucleic acids. It is composed of a cross-linked polystyrene-divinylbenzene copolymer matrix with sulfonate functional groups, which provide a strong anionic exchange capacity. This property allows Bio-Rex 70 to bind negatively charged molecules, such as nucleotides and certain proteins, based on their charge and size. The resin is widely used in applications like DNA purification, protein fractionation, and desalting, offering high resolution and selectivity in the purification process.
The CAS Registry Mumber 9015-69-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,1 and 5 respectively; the second part has 2 digits, 6 and 9 respectively. Calculate Digit Verification of CAS Registry Number 9015-69: (6*9)+(5*0)+(4*1)+(3*5)+(2*6)+(1*9)=94 94 % 10 = 4 So 9015-69-4 is a valid CAS Registry Number.
