Assignee:

Nanjingjinsirui Science & Technology Biology Corp. - Nanjing

International Classification:

C12N 1/20
C12N 9/18
C07K 17/00
C12N 15/64

US Classification:

4352521, 435197, 435 914, 530350

Abstract:

Methods and compositions for cloning a donor DNA molecule into an acceptor vector at a predetermined location are described. The methods are based on homologous recombination mediated by in vitro treatment of the donor DNA and the acceptor vector with an enzyme cocktail containing an exonuclease and a single-stranded DNA binding protein.

B03B 5/28

US Classification:

209173, 209172

Abstract:

Methods and apparatus for separating and removing aflatoxin-contaminated corn from batches of corn by a floating process, thus producing a distinguishable floating mat of contaminated corn and a separate submerged bed of uncontaminated and less contaminated corn. The methods of this disclosure include removing the floating contaminated corn mat by a vacuum mechanism or by liquid flow. The methods reduce the aflatoxin level in the submerged corn bed as much as 80% from the initial aflatoxin level, while removing no more than 15% from the batch of corn.
