摘要:
Examining an object wherein magnetic particles are introduced into at least part of a target area of the object under examination, the target area having a first part with a magnetic field strength that keeps magnetic particles in a non-saturated state, and a second part with a second magnetic field strength that keeps the magnetic particles in a saturated state. A superposed oscillating or rotating magnetic field is generated at least partially in the first part-area to cause at least some magnetic particles to oscillate or rotate. The target area is irradiated with electromagnetic radiation and detected radiation includes reflected or scattered electromagnetic radiation, which is modulated by interaction with rotating or oscillating magnetic particles in the target area. The intensity, absorption or polarization of the detected electromagnetic radiation is determined as a function of change in rotation or oscillation of the magnetic particles due to modulation.

摘要:
A method is provided for enhancing transmembrane transport of exogenous molecules. The method comprises contacting a membrane of a living cell with a complex formed between said molecules and ligands selected from biotin, biotin analogs and other biotin receptor-binding ligands, and/or folic acid, folate analogs and other folate receptor-binding ligands to initiate receptor mediated transmembrane transport of the ligand complex. The method is used for the efficient delivery of peptides, proteins, nucleic acids and other compounds capable of modifying cell function into plant, animal, yeast, and bacterial cells.
摘要:
Conjugates containing glucocerebrosidase and non-antigenic polymers such as polyethylene glycol are disclosed. The conjugates circulate for extended times and have prolonged activity in vivo when compared to unmodified enzymes. The conjugates are useful in the treatment of Gaucher's Disease and have improved enzyme activity at the pH ranges associated with lysosomal, arterial and capillary regions.
摘要:
A substance-conjugated complement component C1q is provided. A substance such as signal emitting substances or cell function regulating substances is conjugated via a sulfur atom to at least one site of the component. The site is not involved in binding immunoglobulins. A marker-labelled complement component C1q is used for measuring a complement-binding antibody, an antigen, a neutralizing antibody or a substance produced internally of and at the surface of a cell or a microorganism by measuring the marker.
