...with the charged groups on the surface of the immobile phase, an anion exchange membrane in this case. The charges on the protein and the membrane must be opposite for the exchange interaction to occur. The support membrane, which has covalently attached positive functional groups, is referred to as an anion exchanger if mobile negatively charged anions will be the exchanged species. Conversely, an exchanger with covalently bound negative groups is a cation exchanger, the mobile counter ions being cations. If an anion exchanger is being used, a negatively charged molecule will bind more avidly if the pH is raised (1). Column chromatography methods are robust and reliable...

...disposed in the environment because it does not break down, dissolve, or rust at any timeframe. The bags could also be made from biodegradable polymer, polylactic acid derived from Lactic acid. The amount of plastic that the world consumes has steadily risen through the past years due to increased industrialization (Freinkel, 2011, p.7). Attribute to success Due to the excessive environmental degradation through the constant use of plastic grocery bags, other alternative measures were incorporated in order to reduce environmental pollution. Use of paper bags made from synthetic natural paper for carrying of goods from one point to the other. Such papers...

...at a similar temperature, they have a tendency to diffuse faster as well (Starr & McMillan 2008). Molecules similar in size and weight disperse faster at greater temperatures, boosting the diffusion rate as the temperature increases (Starr & McMillan 2008). Triggered by concentration gradients, cell diffusion normally occurs through holes or conduits surrounded by proteins. The passage of particular electrolytes, molecules, and other substances may be delayed or barred by electrical charge and size (Star & McMillan 2008). Figure 4. Diffusion *image taken from Google pictures On the other hand, osmosis is a particular form of diffusion. It is basically water dispersal across...

...treated with cp250 and PDGFA were lysed and complexes that were formed were pulled down with an antibody to the receptor. Western blots with antibodies raised against different downstream signaling molecules were performed to identify which components were complexed with the receptor after activation. Controls were performed with cells treated with water. As can be seen in Fig.1A, cp250 and PDGFA both bind to the receptor PDGFR, confirming the first experiment. From Fig.1B, it can be seen that Phospholipase gamma 1 (PLC1) is recruited to the receptor after treatment with either cp250 or PDGFA. From Fig.1C, it can be inferred that autophosphorylation of PDGFR and...

...Osmosis Experiment with Swede In this experiment, I tried to find out the effect of osmosis on slices of swede, a root vegetable, immersed in a pan of water solution. Osmosis is a process where water passes in or out through the tissue of the plant or vegetable. This process explains how plants or vegetables absorb water into its cells or release water from its cells.
How does osmosis take place A plant or vegetable is full of cells that contain water. Each of these tiny cells is...

...by the membrane ultra-structure, the osmotic transport of water is less than expected. Thus it might not show any fragility even at higher ranges of hypotonic saline solution. Moreover, this curve does not represent the typical sigmoid curve of fragility due to data that were derived on the basis of expectations, thus it may represent erroneous calculation and appearance of curve.
Conclusion:
1. Red blood cell membranes are semipermeable due to its membrane structure.
2. They allow entry of water or exit thereof depending on varying concentration of the medium in which they are suspended.
3. A...

...thermodynamic activity, water movement, or osmosis, should go from a low (hypotonic solution) to high concentration (hypertonic solution) of solutes. If no osmosis was observed, the cytoplasm is said to be isotonic to the surrounding solution.
Osmosis happening in cells was replicated in this experiment, with unshelled eggs representing the cells with differentially permeable plasma membrane. The objective of this experiment was to observe the effects of changing the extracellular concentration s to the amount of water...

...Osmosis Jones By 14 March Osmosis Jones Summary and Analysis The movie “Osmosis Jones” is an interesting movie focusing on the human defence mechanism in a very unusual way. It is a science fiction movie released in 2001 based on the human body.
The movie revolves around the character “Frank” and his immune system. However, the hero of the movie is a white blood cell named ‘Osmosis Jones’, who teams up with a pill to eventually save Frank’s life threatened by his poor eating habit.
In my opinion Osmosis Jones is a NEUTROPHILS. They constitute 60% of the body’s white blood cells and are...

...Practice Marketing Marketing is never easy and many marketing need more than just brilliant brains to accomplish their marketing goals. This is because students find out that what they learnt is not enough and sometimes reality plays out differently. I have always faced difficulty in marketing and even small marketing practice sessions with my friends have failed. They say I do not sell my idea to them. This is why marketing students need to develop creativity in order to market successfully. This is where the MH practice marketing game comes in (Practice Marketing). I decided to sharpen my skills with this game.
Practice marketing is a modern, 3D multiplayer marketing strategy game (Practice Marketing). Practice...
