Using finite difference method, we carry out the numerical calculation of the electric field induced by a low frequency magnetic field in a two dimensional stratified biological medium.

That little ball packed with biological material is the medium through which all of our billions of cells coordinate with each other to keep our conscious stable and our bodies responsive.

Objective: To find out a method of extraction and purification of bone morphogenetic protein (BMP) from osteosarcoma cell conditioned medium, and evaluate the biological activity of BMP.
