Protein fragments sequenced in 68 million-year-old Tyrannosaurus rex
In a venture once thought to lie outside the reach of science, researchers from Harvard Medical School and Beth Israel Deaconess Medical Center have captured and sequenced tiny pieces of collagen protein from a 68 million-year-old Tyrannosaurus rex. The protein fragments—seven in all—appear to most closely match amino acid sequences found in collagen of present day chickens, lending support to a...Sheep Anti-Digoxigenin Fab fragments Antibody, AP Conjugated from Roche Applied Science

Contributed by John M. Sedivy, Department of Molecular Biophysics andBiochemistry, Yale University, 333 Cedar Street, New Haven, CT 06510. Genes of higher eukaryotes can be hundreds of kilobases in size. The need to rapidly clone and manipulate DNA molecules in that range has become acute in co...Court bars patent protection for certain gene fragments
At issue was whether certain gene fragment sequences were useful. Most notably whether the gene fragmen...Infertility may result from bone fragments
According to a report infertility in healthy women may sometimes be caused by the presence of fetal bone fragments left embedded in the uterus after a previous abortion. There were evidence over the years that small pieces of fetal bone left behind after abortion cause chronic irritation which could interfere with subsequent pregnancies. Doctors at the University of Ottawa found that in s...Protein Fragments Blocking Cures Alzheimer's Disease
Professor Yadong Huang and his team from Gladstone Institute of Neurological Disease have found that the protein apolipoprotein E (apoE) is responsible for causing Alzheimer's disease //that acts by inactivating the conversion of glucose into energy in Mitochondirial cells due to the protein fragments released from apoE. The apoE protein is found to be responsible for causing Alzheime...
