Abstract:
Antibodies are engineered by replacing one or more amino acids of a parent antibody with non cross-linked, highly reactive cysteine amino acids. Antibody fragments may also be engineered with one or more cysteine amino acids to form cysteine engineered antibody fragments (ThioFab). Methods of design, preparation, screening, and selection of the cysteine engineered antibodies are provided. Cysteine engineered antibodies (Ab) are conjugated with one or more zirconium complex (Z) labels through a linker (L) to form cysteine engineered zirconium-labeled antibody conjugates having Formula I: Ab-(L-Z)p I where p is 1 to 4. Imaging methods and diagnostic uses for zirconium-radiolabeled, cysteine engineered antibody conjugate compositions are disclosed.
Abstract:
A modular platform is provided for rapid preparation of various water-soluble prosthetic groups capable to efficiently introduce 18F into proteins with 18F labelling reagents.
Abstract:
The present invention relates to deuterated and optionally detectably labeled compounds of formula (I) and formula (V): and salts thereof, wherein R1, R2, A, and X10-X19 have any of the values defined in the specification. Also included are pharmaceutical compositions comprising such compounds and salts, and methods of using such compounds and salts as imaging agents.
