Development of standardize protocol for the production of antibodies produced due to hyper immune response in Oryctolagus cuniculus (Rabbit). Rabbits were selected as the ideal model organism because they are easy to bleed subsequently and a better hyper immune response is observed without the death of the organism. The hyper immune response was created against T2 toxin which was diluted; a mixture was made with Freund’s adjuvant (complete and incomplete) and injected into two rabbits kept under observation. One booster dose was given on the 7th day. The injection was given at three different sites and the rabbits were kept for observation. The rabbits were bleeding on 7th, 14th, 21st and 28th day and serum was separated from blood. The serum collected was analyzed for antigen antibody reaction using ELISA. From these studies we have concluded that at 1:100 serum dilutions and 1:50 antigen dilution the antibody-antigen reaction is the highest. It can be further concluded that at the high binding affinity of the toxin to the immobilized antibody, which is evident by the high binding and the low dissociation constant values obtained. This hyper immune serum consists of polyclonal antibodies that can be used for the development of various kit based immunosensors.Keywords

On a global scale, obesity has reached epidemic proportions and is a major contributor to the global burden of chronic disease and disability [1]. Currently, more than one billion adults worldwide are overweight and at least 300 million of them are clinically obese (WHO, 2018). Currently, there are many treatments available for obesity; one such method involves the use of anti-obese molecules. Compounds such as Orlistat, Lorcaserin, Sibutramine, Metformin and Hydroxycitric acid (HCA) are used as anti-obese molecules. Among these, Hydroxycitric acid is the preferred molecule since it shows high efficacy in controlling obesity, with minimal side effects. Several pharmaceutical companies extract HCA from the fruits of Garcinia cambogia, a native tree grown in south India. Due to geographical and seasonal limitation of Gracinia fruits, an alternative method of producing HCA is necessary.Keywords

In this study, BiVO4 and MnCo2O4 were synthesized successfully using hydrothermal and co-precipitation methods. Nanocomposites of BiVO4/MnCo2O4 of varying composition were made by calcination. All the synthesized compounds were well-characterized using PXRD, SEM, EDS and DRS. Powder XRD analysis confirmed the formation of BiVO4, MnCo2O4 and their respective well-defined composites. The band gaps of the materials were in the visible range (1.16–2.36 eV), making them suitable for visible light-driven antibacterial applications to inactivate the Gram-negative bacterium Escherichia coli. The as-prepared composites exhibited superior antibacterial activity (maximum of ~80%) than the parent compounds, possibly due to the synergistic effect.Keywords
