Complement C1q does not bind monomeric beta-amyloid.

The tendency of both labeled and unlabeled beta-amyloid to bind in solution to C1q, the recognition species in the complement cascade, was examined using both hydrodynamic and spectroscopic methods. Potential binding interactions were evaluated using a purified synthetic beta-amyloid 1-40 sequence, alone, and selectively labeled at the amino terminus with spectroscopic probes. The probes permitted both absorbance and fluorescence analyses of beta-amyloid binding interactions.

Vegetative expression of the delta-endotoxin genes of Bacillus thuringiensis subsp. kurstaki in Bacillus subtilis.

Bacillus thuringiensis subsp. kurstaki total DNA was digested with BglII and cloned into the BamHI site of plasmid pUC9 in Escherichia coli. A recombinant plasmid, pHBHE, expressed a protein of 135,000 daltons that was toxic to caterpillars.
