Thromb Haemost 2006; 95: 746–7 Dear Sir, Haemophilia A is an X-linked recessive disorder caused by mutations in the Factor VIII (FVIII) gene and leads to a deficiency of blood coagulation. One in 5000 males is affected by haemophiliaA, and approximately half of all severe cases are caused by a gene rearrangement involving intra-chromosomal homologous recombination between a 9.5 kb region of int...

The genes encoding β-actin (ACTB in human or Actb in mouse) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH in human or Gapdh in mouse) are the two most commonly used references for sample normalization in determination of the mRNA level of interested genes by reverse transcription (RT) and ensuing polymerase chain reactions (PCR). In this study, bioinformatic analyses revealed that the ACT...

Genus and Species. Sus scrofa. Locus. Pig serotonin receptor subtype 2 alpha ( HTR2A) and pig endothelin-B receptor ( EDNRB) . Source and Description of Primers. Heterologous primers for EDNRB were obtained from Leslie Lyons through the CATS project (Lyons et al., 1997) and primers for HTR2A were designed from highly conserved human (M86841) and mouse sequences (X72222). Primers ( EDNRB forward...

Somatic cell hybrid (SCH) panels and radiation hybrid (RH) panels are powerful resources for comparative gene mapping because gene assignments are made without the detection of genetic polymorphism as needed for linkage mapping. A frequently encountered problem, however, is that the gene specific primers may amplify homologous PCR products of equal length from the donor and recipient species of...

Molecular amplification and sequencing of genomic DNA that encodes camel polyubiquitin (PUBC1) was performed by a polymerase chain reaction (PCR) using various sets of primers. The amplification generated a number of DNA fragments, which were sequenced and compared with the polyubiquitin coding sequences of various species. One DNA fragment that conformed to 325 bp was found to be 95 and 88% ho...
