The IgG antibody was separated by using AKTA FPLC by setting the method as:- Column- HiTrap protein G HP 1 mL; Column pressure limit- 0.300 MPa; Flow rate- 1 mL/minute; Sample injection- 0.200 mL; Loading buffer, A- 0.05 M sodium phosphate, 0.15M NaCl, pH 7.0; Elution buffer, B- 0.1 M glycine-HCl, pH 2.7; Neutralization buffer, C- 1 M Tris-HCl, pH 9.0. Different column volume for individual step was then set as- 1 CV 0% B wash and equilibration step; 1 CV 0% B loading; 4 CV 0% B washing; 10 CV 100% B eluting; 5 CV 0% B equilibration. After setting the method, the system was washed with buffer B at the flow rate of

ELISA works on the principle of an antigen binding to specific antibody (lock and key), which can be used as a way to identify quantities of proteins in a small sample of fluid. The specific proteins used in an ELISA are estimated quantitatively. The ELISA test is carried out by incubating the serum that contains the antigen of interest with antibody’s within a well, in order for the antibody’s to bind with the specific antigens. The plate is then washed with a mild detergent in order to remove any proteins that have not been bound. The washing of the plates is carried out between every step in order

Saltwater is being pushed by a moving partition through a membrane. By doing this process, salt is being block by a semi permeable membrane and only pure water flows through it.

The aim of this practical is to identify the presence and the relationship between the antibodies and antigens in the experimental samples, using the ouchterlony method. The antibodies used include rabbit anti-human IgG (α-HuIgG), which is targeted against IgG antibodies. The IgG antibodies in the human serum sample will act as the antigen in this experiment. The other antibody is rabbit anti-human serum (α-HuS), which is targeted against all types of antibodies. Therefore, antibodies in the human serum sample will also be acting as the antigen. Furthermore, it is also aimed to determine which dilution of the human serum sample is optimal for lattice formation (precipitin) with the antibody. This will be achieved through a series of 10-fold dilutions of the samples.

Allow the liquid to pass through it very quickly and give you a lot of surface area on which collect the solid “impurities”

For therapeutic purposes, IgG structure has been modified both chemically at protein level and genetically at DNA level (Milstein & Cuello, 1983). The crucial regions of IgG is the complementarity determining regions, therefore fragments of IgG in form of scFv, F(ab)′ and F(ab)′2 have been generated chemically and genetically. Chemical reduction of F(ab)′2 to F(ab)′ fragments is commonly employed, although it has been reported that the antigen binding activity of F(ab)′ might be lower than the F(ab)′2 and the unreduced intact antibody molecules (Lu et al., 1995). It has also been shown that the structural unfolding of the Fab part of the intact antibody is significantly slower than that of the isolated F(ab)′ fragment which suggests that the structure of the Fab fragment within the intact antibody molecule is stabilized by non-covalent interactions, presumably with the Fc part, missing from the isolated F(ab)′ (Lilie, 1997). Half-antibody fragments obtained by preferential reduction of intact antibody molecules and consisting both of H and L chain are therefore,

After Five minutes of adding the sample, four drops of Running Buffer are added to Buffer Well #2. The buffer hydrates the dried antibody-binding colored conjugates, which migrate to the test and control areas and bind to any HIV and/or treponemal antibodies present, and also bind to the control antibodies, producing one or more colored lines.

Since surrogates are usually measures of symptoms or laboratory biomarkers, they make it easier to quantify

Vortex Infosys Pvt. Ltd. was once known as one of the fast growing and leading application and software Development Company. Vortex Infosys started the outsourcing business in Nepal with the name of Radiant Technologies. With the head office in United States, Australia and United Kingdom the Company performed so well that it became one of the popular and top outsourcing company of Nepal in very short period of time. The organization structure of the company was totally centralized. The Chairman also the investor of the company has all authority to decide the major decisions of the company. In his absence the Managing Director can make all key decisions and most communication is done by one on one conversations with Head of Department (HODs) and Mangers. Due to some management issue as soon as old Director was terminated, Chairman himself appointed his son as new Director of the company without any

this membrane leaving behind a brine solution of high concentration of salts (concentrate) in the feed side of the membrane. The rejected water is normally between 10-50% of the feed water depending on the salt content and pressure of the feed water.

The statement on this discussion board is currently not a fact, since while there are certain advantages for therapeutic use, the current limitations in implementation currently truncate the potential benefits. This said the potential for point of care diagnostic are rather obvious, and with more directed research these can change the way rapid detection test are designed. Sine 1989 when songsilviali and Lachmann described potential for multifaceted used of bispecific antibodies ( BsAbs) as a tool for diagnosis, and treatment of disease, we still face some of the manufacturing problems they did back then, even now with developments in both protein and genetic engendering production for therapeutic use is difficult.

autoantibodies in serum or plasma bind to the antigen-coated surface. The wells are then washed to remove unbound components. In the second incubation, the enzyme-labeled polyclonal antibody to an immunoglobulin (conjugate) binds with surface-bound autoantibodies. After additional washing, specific autoantibodies are traced with substrate during incubation. Addition of a stop solution terminates the reaction, which results in a coloured end product. The amount of conjugate bound is measured in absorbance units (Wild, 2013, p. 9).

Reverse osmosis use water pressure to force water molecule over a membrane.3 First of all, is necessary understand the osmosis process. The phenomenon of osmosis occur naturally in the environment. Osmosis occur in the plants roots, kidneys, and in the blood.10 The natural process consists in a two saline solution.10 However, one saline solution is stronger than other, and it do that the weaker saline solution through for the strong solution.10 Figure 4 displays the normal osmosis process. The lower contaminant concentration is a weak solution, and the higher contaminate concentration is the strong solution. The semipermeable membrane separate the solutions, and this membrane allow some atoms or molecules to pass.10 The dilute solution across the concentrated solution with the intention of equalize concentrations. On the concentrate solution has a pressure for avoid a flow of water molecules.12 This pressure is called osmotic pressure, and it is shown in the Figure 4 form the difference of height of water.

the definitions of medical device and in vitro diagnostic device under new regulations will include device which are not directly indented for medical use e.g. implants for aesthetic purpose, software used for medical device working, also some high-risk device for single use purpose. May include devices used for prediction of disease or health condition.
