incorrect. I think the urea was not able to diffuse through the 20 MWCO membrane because the molecular weight of urea is about 60. This means it is above the molecular weight cut off and cannot diffuse. 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? a. The glucose was able to diffuse because its molecular weight was less than 200‚ while the albumin was much larger than 200 and could not diffuse

Identifying Unknown Bacteria Using Biochemical and Molecular Methods Beginning of Instructor Pages Instructor Pages - - 3 Purpose The purpose of this lab is to introduce a variety of lab techniques to students working on the common problem of identifying an unknown bacterium. This lab helps students develop an understanding of the biochemical and molecular differences in bacteria and introduces the concept of identifying species based on characeristic gene sequences. Students work through

Results(Analysis Questions): Dyes: #4‚ #6‚ and #10 traveled the fastest because they contained a protein with a molecular weight that was smaller than the others. The dye mixtures contained a sample of DNA‚ RNA or other protein. These were negatively charged so that they traveled toward the cathode. There were twelve samples in all‚ labeled #1-#12. Agarose

in the sample. Western blotting is used during this procedure to test that proteins can be indicators of genetic and evolutionary similarity. Results show that the different species of fish contain the myosin light chains that are equivalent in molecular mass‚ which then means they are similar in their evolutionary relationships. Western Blotting is used to Identify a Subunit of Myosin Light Chain in the Proteins of All the Different Fish. Introduction Western blotting is a technique in biological

In active / passive processes‚ the cell provides energy in the form of ATP to power the transport process. Exercise Overview The molecular composition of the plasma membrane allows it to be selective about what passes through it. It allows nutrients and appropriate amounts of ions to enter the cell and keeps out undesirable substances. For that reason‚ we say the plasma membrane is

INTRODUCTION A major obstacle in the successful treatment of cancer is the development of resistance mechanisms to drug treatment. Various cellular changes that have been implicated in the development of drug resistance in cancer cells include: the increased expressions of P-glycoprotein (a multidrug transport protein) and multidrug resistance-associated protein (MRP-1); increased levels of the cellular detoxification protein‚ glutathione; and changes in the expression of apoptosis associated
