Thatâs what would be happening if the earth was flat. The fact that the sun rises and goes up to a zenith and then goes down into the horizon, shows that the earth is spherical in shape. You can travel a thousand miles around the earth and still see this exact same thing, because the earth is spherical in shape.
Immunoprecipitation (IP) is the technique of precipitating a protein antigen out of solution using an antibody that specifically binds to that particular protein.ne of the major technical hurdles with immunoprecipitation is the great difficulty in generating an antibody that specifically targets a single known protein. To get around this obstacle, many groups will engineer tags onto either the C-or N-terminal end of the protein of interest.
An immunomodulator is a drug used for its effect on the immune system. There are two types of such drugs based on their effects:-immunosuppressants. -immunostimulators. http://en.wikipedia.org/wiki/Immunosuppression. Immunosuppression involves an act that reduces the activation or efficacy of the immune system.his is typically done using drugs, but may involve surgery (splenectomy), plasmapharesis, or radiation. A person who is undergoing immunosuppression, or whose immune system is weak for other reasons (for example, chemotherapy and HIV) is said to be immunocompromised.
