摘要:
Disclosed is a conjugate comprising a magnetic material and a physiologically active substance bound to each other through a polyethylene glycol derivative, and a conjugate comprising a magnetic material and a polyethylene glycol derivative bound to each other. According to the present invention, a bioreactor enabling application to or recovery of physiologically active substances under liquid state by utilizing the magnetic properties is provided.
摘要:
A modified lipase, comprising lipase molecules which are partially substituted with an active derivative of a polyalkylene glycol having a hydrophobic group at the terminal end.
摘要:
The invention provides a modified haem which is chemically coupled with a polyalkylene glycol methyl ether or an ω-amino derivative thereof through at least one of the two carboxyl groups in said haem molecule. The modified haem has a peroxidase activity and is soluble in water or various organic solvents. It can be used for detecting peroxides in samples such as blood, food or cosmetics. A process for the production of the modified haem is also disclosed.
