An Automated Procedure for Blood Phenylalanine.
Q UANTITATIV MEAsLIu M EXT of blood I)hellylalauine is at pres eat the most direct approach to the diagnosis of pheniketonuria. Since the disease is relatively rare (estimates of incidence of affected infants 1 :11,000 to 1:20,000) and pathological effects on brain function occur early in infancy, much emphasis has been placed on simple, reliable methods for screening large populations in the n...
متن کاملImproved Procedure for Screening Expression Libraries for Novel Autoantigens
The standard method for immunoscreening of a cDNA expression library is time-consuming becauseof the production of a large proportion of false positives during the first and second round of screening.This problem is more important when a sensitive chemiluminescence detection system is used. Due tothe high sensitivity of the detection system, there is a need to avoid false posi...

متن کاملAn assessment of an automated fluorimetric blood phenylalanine technique for phenylketonuria screening and for accurate estimations.
An assessment of the automated fluorimetric technique for the estimation of phenylalanine, using blood collected and stored on filter paper, indicated that its accuracy and precision compared favourably with those of other methods, including the bacteriological inhibition assay. The method appeared to offer advantages, both in the detection of phenylketonuria and for the more accurate determina...
متن کاملAn Improved Procedure for Metabolism
There are two general types of metabolism experiments: those of relatively short duration covering several periods, each from a few days to a week in length; and those carried out over as long a period as possible. As examples of the first type we have such investigations as the study of the effect of a given substance upon the nitrogenous equilibrium, or the study of the ability of the animal ...
