in this project, 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid, was prepared by the reaction of trimellitic anhydride (tma) with 4,4?-methylenebis(3-chloro-2,6-diethylaniline) (mcdea). the novel poly(amide-imide) (pai) was synthesized from the reaction of 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with mcdea under green condition using ...
A collection of Arabidopsis lines with T-DNA insertions in known sites was generated to increase the efficiency of functional genomics. A high-throughput modified thermal asymmetric interlaced (TAIL)-PCR protocol was developed and used to amplify DNA fragments flanking the T-DNA left borders from approximately 100000 transformed lines. A total of 85108 TAIL-PCR products from 52964 T-DNA lines w...
The fluorometric method for measuring leucine aminopeptidase (EC 3.4.11.1) activity in biological systems, with L-leucyl--naphthylamide as the substrate [C/in. Chem. 16, 412 (1970)] was critically evaluated and refined. In this enzyme assay system, a few precautions are necessary in determining /3-naphthylamine liberated from the substrate by the enzyme action. In water, tris(hydroxymethyl)amin...
Yoghurt-like products has been produced from a blend of soybean, coconut and breadfruit extract in the ratio B20:C20:S60, B20:C30:S50, B30:C20:S50 B30:C30:S40 using Lactobacillus acidophilus on substrates. Two sets yoghurt-like these composites was stored at refrigeration (5oC) then ambient temperature (29±2oC) for 4 weeks 5 days, respectively. They were examined changes physicochemical propert...
Insulin receptor partially purified from human placenta by chromatography on immobilized wheat germ agglutinin was subjected to affinity cross linking to determine the relationship between the subunit structure of the multiple forms of the insulin receptor and their competence to bind insulin and undergo autophosphorylation. It was demonstrated that, whereas the 340-kDa intact receptor undergoe...
Recently, the quality and safety of organic products is the topic of prime concern. While this demand increases since consumer considers organic products are healthier and harmless than conventional products. In the country like India, organic agricultural is not novel and are effectively performs in varied climates such as tribal mountains, mountainous areas and rain-fed zones of the country. ...
