In this video, I discuss the biosynthesis of the third aromatic amino acid, Tryptophan, from chorismate which occurs in the plastid (chloroplast).

In this video, we will discuss how urea recycling between the collecting ducts and the Loop of Henle augments water reabsorption in the Loop's descending limb.

In this video, we explore how casein proteins in dairy products induce an inflammatory response.

As always, the steps of putting a gene insert into vector/plasmid AND nickel affinity chromatography depend on your specific lab and protocol. Here, we look at the general theory of engineering a poly-His tagged protein and Ni affinity...
