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

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
