permeable membrane. There were two parts to the experiment‚ the dialysis tubing lab and the potato lab. In the first experiment‚ the dialysis tubing acted as a semi-permeable membrane. A semi-permeable membrane is a membrane that allows certain substances to pass through. In this experiment‚ several variables‚ including glucose‚ starch‚ and iodine potassium iodide were tested for permeability through the dialysis tubing. In the second experiment‚ several potato tuber cylinders

Finally‚ test the liquid in the bag and beaker for any presence of glucose. Exercise 1B: First‚ soak six 30-cm of dialysis tubing in water. Then‚ take each one out and tie a knot on one end of each piece to make a bag. Pour 25 mL of a different solution (distilled water‚ 0.2 M sucrose‚ 0.4 M sucrose‚ 0.6 M sucrose‚ 0.8 M sucrose‚ and 1.0 M sucrose) into separate bags

fail‚ treatment is necessary‚ and there are only two options: a kidney transplant or dialysis. Dialysis first became a practical treatment in the 1960’s. There are two main types of dialysis‚ hemodialysis and peritoneal dialysis. Both types of dialysis filter blood of harmful wastes‚ extra salt‚ and water. Hemodialysis does this with a machine. Both require a special diet and both types have risks and benefits. Dialysis is not always permanent‚ it depends on if the disease is chronic (long-term) or acute

their individual solute to a lower concentration diffusing threw pores in the dialysis bag. The experiment sought to find out which solutes would diffuse threw the pores of the dialysis bag‚ whether in or out of the bag. The pores and walls of the dialysis bag acted as a permeable membrane‚ like the one found in cells‚ and was the regulator of diffusion for the solutes. Studying the movement of solutes threw the dialysis bag helps better understand diffusion of a cell membrane‚ and the means and solutes

the following items are needed: Dialysis tubing‚ IKI solution‚ 15% glucose/1% starch solution‚ distilled water‚ balance‚ sucrose solutions (0.2M‚ 0.4M‚ 0.6M‚ 0.8M‚ 1.0M)‚ glucose test tape‚ beakers (multiple)‚ petri dish. In the experiment‚ one will measure diffusion through a selectively permeable membrane (dialysis tubing). A 30 cm by 2.5 cm piece of dialysis tubing that has been soaked in water is acquired and made into a bag by tying one end of the dialysis tubing and opening the other end.

However‚ this is the last lab for purification and high level techniques of purification were employed to achieve this. Dialysis was used first‚ lowering the small-molecule concentration within the sample. Finally Affinity Chromatography on a Cibacron blue Sepharose stationary phase.
