The Journal of general physiology, 33(4), 349-362 (1950-03-01)

A crystalline enzyme capable of digesting thymus nucleic acid (desoxyribonucleic acid) has been isolated from fresh beef pancreas. The enzyme called "desoxyribonuclease" is a protein of the albumin type. Its molecular weight is about 60,000 and its isoelectric point is

Characterization of the diatomite binding domain in the ribosomal protein L2 from E. coli and functions as an affinity tag.

Junhua Li et al.

Applied microbiology and biotechnology, 97(6), 2541-2549 (2012-08-29)

The ribosomal protein L2, a constituent protein of the 50S large ribosomal subunit, can be used as Si-tag using silica particles for the immobilization and purification of recombinant proteins (Ikeda et al. (Protein Expr Purif 71:91-95, 2010); Taniguchi et al.

Characterization of diatomite and its application for the retention of radiocobalt: role of environmental parameters.

Guodong Sheng et al.

Journal of environmental radioactivity, 113, 108-115 (2012-06-09)

Clay minerals have been extensively studied because of their strong sorption and complexation ability. In this work, diatomite was characterized by using acid-base titration. Retention of radionuclide (60)Co(II) from aqueous solution by sorption onto diatomite was investigated by using batch
