Several different media were compared by means of surface viable counts of suspensions, in 0.1% solution of bovine serum albumin, of freshly grown BCG, and of BCG resuspended after freeze-drying. The growth of BCG on oleic acid albumin medium enriched with 5% whole blood was best in three respects: from a given inoculum, the colony count was highest; the colonies became visible soonest; and reached the greatest maximum size. The superiority of this medium was particularly evident with inocula of BCG reconstituted after freeze-drying.

SummaryThe biological half-life of prostacyclin in Krebs solution, human cell-free plasma or whole blood was measured by bracket assay on ADP-induced platelet aggregation. At 37°C, pH 7.4, plasma and blood reduced the rate of loss of antiaggregatory activity compared with Krebs solution. The protective effect of plasma was greater than that of whole blood. This effect could be partially mimicked by the addition of human or bovine serum albumin to the Krebs solution. The stabilisation afforded by human serum albumin was dependent on the fatty acid content of the albumin, although this was less important for bovine serum albumin.

Aim: A surrogate matrix is needed to quantify 25-hydroxyvitamin D3 in dried whole blood (DWB). To date, there has been limited guidance on approaches for quantification of endogenous analytes in atypical matrices, such as DWB. Methods: Different surrogate matrices were investigated in a systematic process using an LC–MS/MS assay. Performance assessment was made using quality controls of DWB with different hematocrits. Results & conclusion: Suitability of both phosphate-buffered saline containing bovine serum albumin and washed red blood cells recombined with phosphate-buffered saline containing bovine serum albumin as a surrogate matrix was demonstrated across a range of concentrations and hematocrits representative of expected endogenous analyte samples.
