摘要:
Milk plasma or milk serum is heat sterilized in the liquid phase without denaturation of active milk protein components thereof in the presence of a stabilizer selected from sugar alcohols, disaccharides and mixtures of a sugar alcohol or a disaccharide with an amino acid and at pH 6 to 8. Ammonium sulfate can be added to the heat treated mixture to precipitate the protein components.

A membrane filter of 0.025 to 0.05 mu m pore size is previously treated by passing a solution of a water-soluble high molecular substance such as albumin, dextran,polyvinylpyrrolidone, polyethyleneglycol, gelatin or the like through the filter. Employing the filter thus treated, a solution of human growth hormone (HGH) is filtered at high recovery rate of HGH activity to remove Creutzfeldt-Jacob disease pathogen which may exist in HGH preparations.
摘要:
Primers for a polymerase chain reaction are prepared by treating a double-standard DNA fragment with an exonuclease. DNA is amplified in vitro by the polymerase chain reaction using such primers. Chromosomal genes are amplified by carrying out the inverted polymerase chain reaction using as a primer, a DNA fragment obtained by treating a double-stranded DNA fragment with an exonuclease capable of digesting one chain of the double-stranded DNA in a manner such that mononucleotides are released therefrom in the direction from the 5′ terminus to the 3′ terminus and, as a template, a circular DNA obtained by cleaving the chromosomal gene with a restriction enzyme and subjecting the resultant fragment to self-ligation.
摘要:
A polymeric carbonyl diimidazole derivative of the formula:- wherein R is the residue of a water soluble polymer of molecular weight 2000 to 10,000, eg. monomethoxy polyethylene glycol, is produced by reacting the polymer at a concentration of 0.15 to 0.35M with carbonyldiimidazole at a concentration ratio of 1:1 to 1:3. A modified superoxide dismutase of the formula:-
R-O- -NH-SOD is produced by reacting said derivative with superoxide dismutase in the presence of a 0.1M to 0.5M concentration of an alkaline buffer having a pH of 9 to 11 at a temperature of 30 to 70 o C.

摘要:
The present invention relates, in one embodiment thereof, to a peptide having affinity for human transferrin receptor, which can be used for binding to any of compounds (a protein, a nucleic acid, a low molecular weight compound, and the like) that should be caused to function in the central nervous system (CNS), in order to allow the compound to pass through the blood-brain barrier, and the use of the peptide. The peptide is, for example, a peptide having the amino acid sequence selected from the group consisting of amino acid sequences set forth in SEQ ID NOs:3 to 7 and 55, or a mutant thereof.
