alpha-1-Protease inhibitor phenotypes and serum concentrations in Thailand. 1980

P Pongpaew, and F P Schelp

alpha-1-Protease inhibitor (A1PI) Pi phenotypes were determined in 429 individuals from Bangkok and 423 from the rural area of the northeast of Thailand by isoelectric focusing on thin-layer polyacrylamide gel. Variation was more marked in the Bangkok population. In the rural area, with an exclusively northeastern Thai population the Pi-alleles M, S and Z were detected. A1PI serum concentrations measured by electroimmunoassay were slightly higher in Thai than the values reported from European countries; children with PiM from rural areas had slightly higher A1PI serum concentrations than PiM children from Bangkok.

UI MeSH Term Description Entries
D007122 Immunoelectrophoresis A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D010641 Phenotype The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment. Phenotypes
