    INTRODUCTION:
    A few decades ago, it was realized that certain proteins could be used as pharmaceutical agents for the treatment of human diseases. e.g. insulin for diabetes mellitus, interferon for viral diseases. However the availability of such therapeutic/ pharmaceutical products was limited due to costly and cumbersome procedures involved in their isolation. Further, their use in humans was associated with several complications. For instance, administration of pig insulin to diabetic patients results in the development of antibodies.

    The advent of recombinant DNA technology heralded a new chapter for the production of a wide range of therapeutic agents in sufficient quantities for human use. The commercial exploitation of recombinant DNA  (rDNA) technology began in late 1970s by biotechnological companies to produce proteins.There are around 400 different proteins being produced  by rDNAtechnologyand as of now around 30 have been approved for human use.

  • Bio Fertilizers

    The worldwide spread of inflation, initiated by several fold rises in Petroleum price thereby depicting its striking influence on the prices of chemical nitrogenous fertilizers, the prices of nitrogenous fertilizers have nearly doubled during the last 3-4 years. This has necessitated to search for cheaper source of nitrogen to meet the needs of crops. This has rejuvenation of soil microbiology to tap out the biological fixation of nitrogen.

    ABSTRACT:
    The environmental biotechnology employs the application of genetic engineering to improve the efficiency and cost which is essential to the future wide spread exploitation of microorganisms to reduce the environmental burden of toxic substances. Now a days it can be achieved by bioremediation, is the process by using microorganism metabolism to remove pollutants and organic substances. It may be employed to attack specific soil contaminants, such as degradation chlorinated hydrocarbons by bacteria.

    INTRODUCTION:
    A biosensor is a device that uses specific biochemical reactions mediated by isolated enzymes, immunosystems, tissues, organelles or whole cells to detect chemical compounds usually by electrical, thermal or optical signals (1). Or in other words, Sensor that integrates a biological element with a physiochemical transducer to produce an electronic signal proportional to a single analyte which is then conveyed to a detector.

    INTRODUCTION:
    Cryopreservation and lyophilization of plant germplasm has obvious advantages over in vitro storage in term of space saving and improved phytosanitation. We compared cryopreserved and lyophilized leaf as sources for genomic DNA isolation by CTAB protocol and PVP protocol.Our results showed that cryopreservation of leaf tissue yielded high molecular weight genomic DNA. The DNA was suitable for restriction-enzyme digestion and as a template for polymerase chain reaction (PCR) amplification. While these results rule out cryopreserved  tissue as a source for DNA isolation, the ability to freeze-dry, powder, and efficiently store voluminous tissue samples for later use in DNA and protein isolation could be of great benefit to laboratories involved in  molecular genetics and molecular biology.

    ABSTRACT:
    A Genetically Modified (GM) tomato, or transgenic tomato or genetically engineered is a tomato that has had its genes modified, using genetic engineering. The first commercially available genetically modified food was a tomato engineered to have a longer shelf life. Currently there are no genetically modified tomatoes available commercially, but scientists are developing tomatoes with new traits like increased resistance to pests or environmental stresses. Other projects aim to enrich tomatoes with substances that may offer health benefits or be more nutritious.

    ABSTRACT
    Enzyme-linked immunosorbent assays (ELISAs) are plate-based assays designed for detecting and quantifying substances such as peptides, proteins, antibodies and hormones. Other names, such as enzyme immunoassay (EIA), are also used to describe the same technology. In an ELISA, an antigen must be immobilized to a solid surface and then complexed with an antibody that is linked to an enzyme. Detection is accomplished by assessing the conjugated enzyme activity via incubation with a substrate to produce a measureable product. The most crucial element of the detection strategy is a highly specific antibody-antigen interaction. There are three methods of ELISA. Each type of ELISA can be used qualitatively to detect the presence of antibody or antigen. Alternatively, a standard curve based on known concentration of antibody or antigen is prepared, from which the unknown concentration of a sample can be determined.

    Abstract
    Green biotechnologydeals with the use of environmentally-friendly solutions as an alternative to traditional agriculture, horticulture, and animal breeding processes. An example is the designing of transgenic plants that are modified for improved flavor, for increased resistance to pests and diseases, or for enhanced growth in adverse weather conditions. Genetically enhanced crops are one tool that could contribute to a more harmonious balance between food production and our surrounding environment.  The overall message is that biotech plants can, and already do, contribute positively to reducing CO2 emissions and anticipating the impact of climate change on food scarcity. This will increase as they are more widely adopted. This document aims to provide background information about the role green biotech currently plays, and can play in future, in helping to combat climate change.
