Introduction
Conjugation of enzymes to antibodies involves the formation of a stable, covalent linkage between an enzyme [e.g., horseradish peroxidase (HRPO), urease, or alkaline phosphatase] and an antigen-specific monoclonal or polyclonal antibody in which neither the antigen-combining site nor the active site of the enzyme is functionally altered. The chemistry of cross-linking HRPO or urease to immunoaffinity purified monoclonal or polyclonal antibodies (IgG) is presented in. The chemistry of cross-linking alkaline phosphatase to antibodies is presented in. The enzyme most commonly used in the immunoreagent (the antibody enzyme conjugate) preparation is horseradish peroxides. This enzyme is cheap and can be attached to the immunoreagent by a variety of methods. Moreover many chromogenic substrates for it are also available.

ABSTRACT:
The validation is a Fundamental segment that supports to a commitment of company towards quality assurance. It also assures that product meets its predetermined quality specification and quality characteristics. Validation of individual step of manufacturing is called as process validation. This Article concerns with the validation of biotechnological process. It is generally complex than validation of traditional synthetic or naturally occurring small molecules of drugs. Its level of complexity depends upon type of biotechnological products. The validation of biotechnological process has 3 Basic aspects they are Risk factors that are needed to be addressed, analytical tools necessary for validation and validation of unit operations.

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.

Abstract:
The vast amount of information available through the human genome project is going to have a major impact on medical science. However, the mere sequence information of the whole genome does not answer all our questions. What is required at this stage is a complete understanding of the function of genes and other parts of the genome so as to uncover how sets of genes and their products work together in normal and diseased conditions. One major requirement for these studies is the development of high-throughput technologies. DNA microarrays are some of the most powerful and versatile tools available, and there are several applications of microarray technology e.g. cancer.

ABSTRACT
Hepatitis C virus (HCV) is a major human pathogen associated with life-threatening liver disease, affect 170 million people worldwide. Hepatitis C virus (HCV) envelope proteins mediate the entry of virus into cells by binding to cellular receptors, resulting in fusion of the viral membrane with the host cell membrane and permitting the viral genome to enter the cytoplasm. Entry inhibitors would inhibit the viral entry itself.

1. Introduction:
Natural dyes are known for their use in colouring of food substrate, leather, wood as well as natural fibers like wool, silk, cotton and flax as major areas of application since ancient times. Natural dyes may have a wide range of shades, and can be obtained from various parts of plants including roots, bark, leaves, flowers, and fruit (Allen 1971). Since the advent of widely available and cheaper synthetic dyes in 1856 having moderate to excellent colour fastness properties, the use of natural dyes having poor to moderate wash and light fastness has declined to a great extent.

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.
EFFECT OF LYOPHILIZATION AND CRYOPRESERVATION ON PLANT LEAVES OF TERMINALIA ARJUNA TERMINALIA CATAPPA, TERMINALIA CHEBULA, JATROPHA GOSSYPIFOLIA, JATROPHA CURCAS

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.
