what is the function of a well in electrophoresis?

The well in the chamber is to contain the buffer solution. The well in the agarose is to contain the sample.\n is that what you needed??

What Is It??\nHello, everyone, and welcome to the wonderful world of chromatography! What is chromatography, you ask?? Well, quite simply, it is a broad range of physical methods used to separate and or to analyze complex mixtures. The components to be separated are distributed between two phases: a stationary phase bed and a mobile phase which percolates through the stationary bed. \n  \n  \nHow Does It Work? Like Magic!\nA mixture of various components enters a chromatography process, and the different components are flushed through the system at different rates. These differential rates of migration as the mixture moves over adsorptive materials provide separation. Repeated sorption/desorption acts that take place during the movement of the sample over the stationary bed determine the rates. The smaller the affinity a molecule has for the stationary phase, the shorter the time spent in a column.

I hope i understand your question-\nForces: Osmosis = 1\n              Facaltative diffution =2\n               \n2.Thier is the NA/K pump in cell membranes that control water level\n1.The albumin in tissues that regulates homeostasis\n1 and 2.There is the CL pump that also regulates water in the cell membrane. \nThink those are the main ones

Electrophoresis is a process used in molecular biology labs where a given protein, often of unknown composition, is migrated through a gel with polarity;positively charged on one side and negatively on another, such that the protein, in this case DNA, is migrated through the gel to create "bands" (visual horizontal lines).  The distance that the DNA fragment migrates is inversely proportional to the (log 10) of their molecular weight.  This enables the researcher to deduct the sequence of the codons within the particular DNA sequence and this is critical in mapping genes and sequencing.\n\nAgarose gel electrophoresis is an easy way to separate DNA fragments by their sizes and visualize them. It is a common diagnostic procedure used in molecular biological labs.\nThe technique of electrophoresis is based on the fact that DNA is negatively charged at neutral pH due to its phosphate backbone. For this reason, when an electrical potential is placed on the DNA it will move toward the positive pole (source:  http://www-biology.ucsd.edu/classes/bicd101.SP06/Electrophoresis_of_DNA.doc)\n\nSee this link for more info:\nhttp://www.vivo.colostate.edu/hbooks/genetics/biotech/gels/agardna.html

The second one works really well, but not with all proteins.  I think the second one can look at several proteins at once too.  It's better suited for complex mixtures.

it is produced by the kidneys and it's function is to regulate the production of red blood cells, if the kidney is damaged or unhealthy it cannot secrete this substance causing anemia.

The function is as a power source. Energy in the\nform of chemicals with highly active electrons are\nstored in the mitochondria. Here is an excellent site.\ncellbio.utmb.edu/cellbio/\nmitochondria_1.htm#\npowerhouses\n A fascinating little tidbit is that it is the only\nplace outside the nucleus that contains DNA. Thus its\nname, mitochondrial DNA and it's only passed down\ngenetically thru the mother.

emm...is this your homework??well..it seems that the question is not from you (individually). Hmm..for more understanding, check out this website:\n\nhttp://faculty.clintoncc.suny.edu/faculty/Michael.Gregory/files/Bio%20101/Bio%20101%20Lectures/Biochemistry/biochemi.htm\n\nI hope it solves your dillema, good luck :)

Dialysis tubing is tubing with a semi-permeable exterior, thus allowing the osmosis of small molecules, such as water, through its wall, while preventing larger molecules such as starch and proteins from passing through. It is used as a filter for dialysis.\nTypically a solution of several types of molecules is placed into a semipermeable dialysis bag, such as a cellulose membrane with pores, and the bag is sealed. The sealed dialysis bag is placed in a container of a different solution, or pure water. Molecules small enough to pass through the tubing (often water, salts and other small molecules) tend to move into or out of the dialysis bag, in the direction of decreasing concentration. Larger molecules (often proteins, or polysaccharides) that have dimensions significantly greater than the pore diameter are retained inside the dialysis bag.

A well is a man-made place for getting water from the earth.  A spring is a natural place where underground water comes to the surface

Ionophores- They havea negatively charged channel that allows the solute to enter\n\nFacilitated diffusion- Essentially they capture a solute and tug it into the cell.\n\nactive transport- i believe they look similarly to proteins that facilitate diffusion

Keep the cell contents bound together,exchange gases and excreta,Semi permeable entry i.e. it protects the cell by allowing only some Substances to enter the cell, maintains the shape of the cell and helps in transfer of water from cell wall as it has hydrophilic proteins in plants

Typically labs have densitometers for gel electrophoresis analysis.  There has also been increasing use of capillary electrophoresis systems for IFE/s and SPE.

Its a buffer and a metal chelating agent. \nIt prevents metallo proteases and nucleases from funcitoning fully as well as stabilizing the pH of the buffer. \n\nRegards

It's a relatively inexpensive way to measure the absorbance of aqueous solutions in the visible region of the spectrum.  Absorbances can be related to concentrations, so this is heavily used in quantitative chemical analyses.

During electrophorsesis or the electrical separation of protein substances you need a single point of entry into the gel so that the protein or material to be separated can effectively be manipulated by the electrical field created in the gel medium.  The substances then separate themselves by way of electrical charge on the molecule, pH of the gel used, and the strength of the electrical current passed through the gel.  You want the separation to occur in a controlled manner so you can later stain the gel medium with a protein or suitable dye and visualize the different substances separated into unique patterns so they can be identified against a known sample of substance.  A machine called a densitometer can scan the gel medium and calculate the % of each population of substances stained in the gel.
