Answer to Question #43333 in Biochemistry for Sumit
Chemical method to determine the number of polypeptide chains in a protein.
The chemical methodsare usually employed for amino acids analyses, end-group analysis, and quantitative analysisfor specific prosthetic groups. However, the presence of subunits can be established with the help of other methods: gel chromatography, sedimentation velocity, sedimentation equilibrium, and electrophoresis under nondenaturing conditions, followed by a second dimension under denaturing conditions
Once again, excellent work. Their high quality of work and reasonable price allowed me to focus on studying for a test instead of having to come up with extemporaneous lab work that is several chapters ahead of where the test is.
Would highly recommend their work.
