BACKGROUND The polymorphism of the protein tyrosine phosphatase nonreceptor 22 (PTPN22) gene, which encodes an important negative regulator of T cell activation, has been reported to be associated with susceptibility to Graves' disease (GD) in Caucasians. The objective of this study was to investigate whether PTPN22 gene polymorphisms confer susceptibility(More)
The authors report a 36-year-old man with exertional myoglobinuria and muscle cramp without hemolytic anemia or CNS symptoms. They found a deficiency of phosphoglycerate kinase (PGK) activity in muscle and erythrocytes and a 4-base pair deletion in exon 6 of the PGK gene. This mutation may cause a frameshift, yielding an abnormal stop codon in exon 6 by(More)
Most in vitro protein synthesis systems require a supply of GTP for the formation of translation initiation complexes, with two GTP molecules per amino acid needed as an energy source for a peptide elongation reaction. In order to optimize protein synthesis reactions in a continuous-flow wheat embryo cell-free system, we have examined the influence of(More)
Synthetic DNA libraries encoding human antibody VL and VH fragments were designed, constructed, and enriched using mRNA display. The enriched libraries were then combined to construct a scFv library for mRNA display. Sequencing revealed that 46% of the library coded for full-length scFvs. Considering the number of molecules used in mRNA display, the size of(More)
