In this chapter we have provided instructions for transforming yeast by a number of variations of the LiAc/SS-DNA/PEG method for a number of different applications. The rapid transformation protocol is used when small numbers of transformants are required. The high efficiency transformation protocol is used to generate large numbers of transformants or to deliver DNA constructs or oligonucleoti...

By using a benzethonium chloride concentration 12-fold that described originally (Clin Chem 1979;25:1317-9), we developed a reliable method suitable for routine measurement of total protein in cerebrospinal fluid. Only 10 microL of sample is required. Reactivity to immunoglobulin G (IgG) and to albumin (Alb) is similar, as is necessary for specimens that can have very varied IgG/Alb ratios. The...

OBJECTIVES Recombinant protein production processes in Escherichia coli are usually operated in fed-batch mode; therefore, the elaboration of a fed-batch cultivation protocol in microtiter plates that allows for screening under production like conditions is particularly appealing. RESULTS A highly reproducible fed-batch like microtiter plate cultivation protocol for E. coli in a micro-bioreac...

164 Abstract We have developed an allotyping assay for detection of four HLA DRB1*01 group alleles based on polymerase chain reaction and solution hybridization in a microtiter plate. Using group specific primers a region within exon 2 of HLA DRB1 gene was amplified by PCR. Labeling of PCR product was achieved by adding small amount of Dig-dUTP in place of dTTP. Labeled PCR product was hybridiz...

BACKGROUND [FeFe] hydrogenase enzymes catalyze the production and dissociation of H(2), a potential renewable fuel. Attempts to exploit these catalysts in engineered systems have been hindered by the biotechnologically inconvenient properties of the natural enzymes, including their extreme oxygen sensitivity. Directed evolution has been used to improve the characteristics of a range of natural ...

In this study, siderophore production by various bacteria amongst the plant-growth-promoting rhizobacteria was quantified by a rapid and efficient method. In total, 23 siderophore-producing bacterial isolates/strains were taken to estimate their siderophore-producing ability by the standard method (chrome azurol sulphonate assay) as well as 96 well microplate method. Production of siderophore w...
