How well did the results compare with your prediction? Urea molecules are too large (molecular weight of Urea is 60.07 g/mol) to pass through the 20 MWCO membrane. The results of the experiment correlated with my prediction. 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? As expected‚ glucose‚ with a molecular weight of approximately 180 g/mol‚ readily diffused across the 200 MWCO membrane;

Which MWCO dialysis membranes allowed both of these ions through? 50‚ 100‚ and 200 4. Which materials diffused from the left beaker to the right beaker? NaCl‚ Urea‚ and Glucose at MWCO 200 5. Which did not? Why? Albumin‚ too large to diffuse Activity 2: Simulating Dialysis 1. What happens to the urea concentration in the left beaker

concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration to areas of lower concentration. • Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? My prediction was correct. The molecular weight of urea is 60.07 and

WESTERN BLOTTING (Written Report) I. PRINCIPLE Western blotting is a method for identifying a specific protein in a complex mixture and simultaneously determining its molecular weight. In Western blotting‚ proteins are electrophoresed into a gel‚ as the proteins migrate through the gel they are separated based upon size and charge. Characteristically‚ smaller proteins migrate through the gel faster than larger proteins. Sufficiently separated proteins in an SDS-PAGE can be transferred to a

The most important will be the field of molecular imaging that is understood as the visualization‚ characterization and measurement of biological processes at the molecular and cellular levels in humans and other living systems. The techniques used for it include radiotracer imaging/nuclear medicine‚ magnetic resonance imaging (MRI)‚ optical imaging‚ ultrasound and others. Molecular imaging that is now used mostly in scientific laboratories will be probably

Glucose was able to diffuse through the 200 MWCO pore because it was small enough‚ having a molecular weight of 180.2 g/mol.
