To optimize conditions for sample collection, preparation, storage, and analysis and to assure the validity of our previously published liquid chromatographic (LC) method for carbamate analysis in tissue, stabilities of 16 N-methylcarbamates in beef,

The elm spanworm, Ennomos subsignarius (Hubner), is known to be more vigorous and develop faster when reared on juvenile rather than mature leaves of the hickories, Carya spp., and oaks, Quercus spp., two of its principal hosts in the Southern United

A high performance liquid chromatographic (HPLC) method for determining the concentration of trace amounts of benzo[a]pyrene (B[a]P) in particulate matter from combustion of forest fuels was validated. Particulate matter was prepared for analysis by

A survey was made of the concentration of N, P, K, Ca, Mg, Al, Mn, Zn, Fe, and Cu in inner bark and needles of loblolly pines and the soils in which they grew. Concentrations of K, Al, and Mn in inner bark differed significantly with plots on four so

The concentrations of K, Ca, N, Mg, P, Al, Mn, Na, Zn, Fe, Cu, ash, and H2O in the inner bark of mature loblolly pines growing on three soil series were determined over a 1-year period. Concentrations of ash, H2O, Ca, Al, Mn, and Fe differed signific

A reference radioassay for vitamin B12 in serum, in which human serum is used as binder and DEAE-cellulose is used to separate free and bound B12, was compared (194 sera) with a packaged kit (" Phadebas B12 Test"), in which intrinsic factor is used a

The competitive inhibition radioisotopic assay of serum vitamin B12 has been adapted for the measurement of cerebrospinal fluid B12. The relatively low CSF B12 levels (1/20 to 1/30 that of serum) necessitated increased sensitivity. This was achieved

SummarySaturation analysis or competitive inhibition utilizing bacteria (L. casei) as the specific binder permitted the measurement of serum folate. Unlike conventional microbiologic techniques, organism growth rate was not determined. This new “ra

The present study delineates the application of the radioisotopic competitive-inhibition assay for the measurement of vitamin B12 in tissues. The extraction of endogenous B12 from tissues was shown to be simple and complete. Proportional dilution stu

The radioisotopic saturation analysis assay has demonstrated its applicability to the determination of serum vitamin B12 levels; however, several potential problems have existed in the assay. These are the basis of this report. It has been demonstrat
