In a typical expression vector, the polyhedrin (polh) gene, which codes for the major protein in the occluded form of the virus, is replaced by a transgene of interest. The transgene can then be expressed under the control of the polh promoter to achieve maximal protein expression in their natural hosts, insect cells.
Commercial rubber is a product that is important to the convenience of our everyday lives. We find it in our tires, our shoes, our flooring, adhesives, and in a plethora of small items that are all made from rubberâwhile the products themselves may be small in size, their significance is usually much larger. In any case, rubber is made from two main sources: naturally-produced latex and petroleum.
These 10 facts about space will blow your mind. Rubberwood is taken from Hevea brasiliensis, also called the rubber tree or Para rubber tree. These trees are cultivated for their natural latex sap, but they also yield a high quality wood with a tight grain that can be used in a wide range of applications.Despite the name, rubberwood does not bounce or stretch; the name is a reference to the parent tree.In addition to being beautiful, this wood is also an ecologically sustainable timber, making it popular with people who are concerned about the health of the world's forests.ubberwood is a waste by-product of mono-culture which is destroying our environmental diversity! The wood really isn't that interesting in grain or color-it is all of the toxic finishes (stains, paints, polyurethanes) that they put on it that make it somewhat appealing to consumers.
