Identification of Mycobacterium tuberculosis DNA in a pre-Columbian Peruvian mummy.
The existence of tuberculosis in the pre-Columbian Americas is controversial because the morphology of the lesion is not specific, the organism is culturally nonviable in ancient tissues, andExpand

The hagfish slime gland: a model system for studying the biology of mucus.
The hagfish slime gland may provide a model system for studying certain aspects of the biology of mucus. Mucus is obtained in nonhydrated form by electrically stimulating the anesthetized hagfish andExpand

A lock-docking oligo(dT) primer for 5' and 3' RACE PCR.
We describe a method that can be used to obtain and sequence 3' and 5' ends of cDNA transcripts directly from PCR products. The method employs a modified oligo(dT) primer that enables it toExpand

The specificity of UDP-glucose 4-epimerase from the yeast Saccharomyces fragilis.
1. 1. The reactivity of UDP-glucose 4-epimerase (EC 5.1.3.2) from the yeast Saccharomyces fragilis toward 11 analogs of UDPG has been examined. The compounds tested involve stereochemicalExpand
