A new nonisotopic detection method based on time-resolved fluorescence for nucleic acid hybridization assays with alkaline phosphatase labels has been developed: enzyme-amplified lanthanide luminescence (EALL). EALL combines the amplification of an enzyme label with the sensitivity and background elimination of time-resolved fluorescence detection of lanthanide ion luminescence. The detection s...
Nowadays, genetic engineering methods are able to reduce the time of breeding programs for improvement of fruit trees, as well as offering a focused breeding system. The purpose of the present investigation was to study the factors that affect Agrobacterium tumefacience mediated transformation of two pear cultivars: Bartlett and Harrow Delight. Two explants (leaves and axillary shoot meristems)...
the human granulocyte-macrophage colony stimulation factor (hgm-csf) gene was cloned in the pet 23a( +) expression vector under the control of strong bacteriophage t7 transcription and translation signals. the hgm-csf gene was transferred into e. coli strainbl21 (de3)plyss andiptg was used for induction of gm-csf gene. production of the target protein was obtained as revealed by elisa and weste...
Immunoassays are among the most powerful and useful techniques for analysis of biological materials. There are numerous variations in which immunoassays can be performed. Coupled with enzyme, using chromogenic substrates, the enzyme immunoassay technique is used to trace the target antigen in tissues. The technique also is used to measure the concentration of antigen in tissue extracts. This ch...
