Immunoblotting

Immunoblotting, often known as western blotting, is a technique for separating proteins by molecular weight. Two gels are created in this technique: a stacking gel pH (6.8) and a separating gel pH (8.8). The samples are put onto an acidic stacking gel, which separates proteins poorly but allows them to form narrow, highly defined bands. Smaller proteins travel quicker than larger protein molecules on a separating or resolving gel used to separate proteins based on their size. When voltage is supplied to the protein before loading, it is denatured and has a negative charge that travels towards the positive electrode. After the protein separation, the gel is sliced and inserted in a sandwich of fibre pad and filter sheets with a membrane (PVDF or nitrocellulose) and placing it in the tank with the transfer buffer with overnight transfer of protein to the membrane. After the protein has been transferred to the membrane, it is blocked by blocking solution to prevent antibodies from attaching nonspecifically to the membrane. Washing is done three times at a 10-minute interval after blocking. After that, the primary antibody is added for four hours, and then washing is done three times at a five-minute interval. The membrane is then added with a secondary antibody. The membrane is then detected using the label antibody and an enzyme such as horseradish peroxidase (HRP), which is identified by the signal it creates matching to the target protein's position. This signal is recorded on film, which is typically developed in a dark environment and hence blots are developed Summer Training in Biotechnology and Bioinformatics in Lucknow Experiome Inc.

The requirement to test more proteins in fewer samples at the same time has prompted continued research towards increasing the sensitivity and speed of blotting techniques. Nonspecific interactions create false positives, which are eliminated by double blotting. Specific protein-protein interactions can be detected via Far-Western blotting. Proteins that interact with certain DNA sequences are identified by southwestern blotting. Multistrip blotting improves throughput while reducing variability between blots. New methods are being developed to lower the amount of protein required to produce a signal and to improve Western blotting's quantitative capabilities Summer Training in Biotechnology and Bioinformatics in Lucknow Experiome Inc.

Use of Genetically Engineered Cyanobacteria in Therapeutics Spirulina is a blue-green algae or cyanobacteria which is found in high-salt alkaline water, subtropical and tropical places such as America, Mexico, Asia, and Central Africa.   It’s asexual reproduction reduces the danger of gene escape into the food chain, as well as the accompanying food security and regulatory concerns. It contains a lot of macro and micronutrients, important amino acids, proteins, lipids, vitamins, minerals, and antioxidants. With these characteristics, photosynthetic cyanobacteria have been used in a variety of industries, including food, health, and pharmaceuticals. It is consumed mainly in central Africa and later NASA started using spirulina as a nutritional supplement for astronauts on space missions. It gained attention for therapeutic benefits like hypercholesterolemia, hyperglycerolemia, cardiovascular diseases, inflammatory diseases, allergies, cancer and viral infections.  Spirulina, as a plan

Ethics and Requirements of Plant Tissue Culture Laboratory | Experiome Inc

  Ethics and Requirements of Plant Tissue Culture Laboratory Plant tissue culture generally refers to   in vitro culture of all plant parts under sterile conditions. Basic facilities are must in the laboratory where tissue culture technology is to be performed. This includes general cleaning and media preparation, sterilization, storage, sterile transfer, observation / data acquisition, and environmentally controlled incubator or culture room areas. The most important work area is the Cultural Transfer Office, where   core activities take place. Plant tissue culture should be cultured for a specified period of time under well-controlled temperature, humidity, airflow, and light quality. Plant culture techniques require a variety of organic and inorganic chemicals to prepare the   culture medium. The growing room is an equally important area where plant cultures are maintained under controlled environmental conditions for optimal growth. After in vitro culture of plants they are transfe

Macronutrients or micronutrients are the two types of nutrients. Requirements of macronutrients including fats, proteins, and carbohydrates are relatively higher to that of micronutrients including several vitamins and minerals. In comparison, if the amount of micronutrients in the diet is low, it has an impact on the child's physical and mental development. Vitamin A is a lipid-soluble vitamin that is required for cell growth, metabolism, immunological function, eyesight, and reproduction. It is absorbed in the duodenum and stored in hepatic stellate cells, as well as in adipose tissue and the pancreas in small amounts. Vitamin A is found naturally in dark leafy greens, orange-colored vegetables, milk products, liver, and fish. Vitamin A intake should be around 200 micrograms per day for children aged 1 to5, 70
