PCRM develops world's first cruelty-free insulin assay

... and competitively priced, researchers and medical labs will use it," said Barnard. "We have proven that if researchers are willing to make the effort, there are effective, humane alternatives to animal-based assays and other testing procedures--alternatives that could help save the lives of millions of p...

Use of PET can reduce, may eliminate more strenuous drug development trials with animals

...many as 12,000 academic and private animal imaging labs in the world and that more than 200 may do small animal PET routinely. Through small animal imaging research, Welch and his researchers gained more of an understanding about titanium anti-cancer drugs and new techniques for PET imaging with 45Ti, wh...

...ush, professor and director of the plant pathology labs in Bushland and Amarillo. "We do all of our work in the greenhouse and laboratory," he said. "Here, we have to have an understanding of everything, from the crop growing in the field to the molecular aspects of the pathogen. That makes our program t...

Cancer related gene p53 not regulated as indicated by previous tissue culture research

...ersion. Previous tissue culture studies by several labs around the world indicated that tinkering with the tail end prevented the protein from being flagged for degradation or activation. Instead of accumulating in mouse cells and halting cell division in the genetically engineered mice, the altered p53 p...
