Aim The aim of the experiments to be carried out is to determine the kinetic parameters, Km and Vmax, of Alkaline Phosphatase. Theory, Principles and Application of Principles Enzymes are a huge varying group of proteins which are needed to carry out essential metabolic functions in cells. Substrate-specific enzymes, like Alkaline Phosphatase, act as catalysts lowering the needed activation energy to convert the substrate to product. Enzymes are made up of amino-acids and amino-groups have side chains

Trademark Dilution (Victoria Secrets Case) In today’s world consumers purchase products on the basis of brand name and trade symbol which accompanies the product, rather than buying the product on the basis of usefulness and quality. Therefore the protection of the trademark is important. Trademark dilution is a claim which owner of well-known trademark can make to prohibit others from using a mark which decreases or lowers the value or distinctiveness or defames the reputation and uniqueness of

Serial Dilution Many of the laboratory procedures involve the use of dilutions. It is important to understand the concept of dilutions, since they are a handy tool used throughout all areas of the clinical laboratory. These dilutions have to be considered as they make a quantitative difference in what is going on. nA serial dilution is any dilution where the concentration decreases by the same quantity in each successive step. If an answer contains a one/10 dilution the quantity represents 1 a part

Hem dilution: donating your own blood during surgery. Immediately before surgery, some of your blood is taken and replace with IV fluids. After surgery, your blood is filtered and returned to you. This process dilutes your own blood so you lose less concentrated blood during surgery. The disadvantage of this process is that only a limited amount of blood can be removed, and certain medical conditions may prevent the use of this technique. Apheresis: donating your own platelets and plasma. Before

whether the objective evidence of actual damage to the economic value of a famous mark rather than a presumption of damage from subjective probability standard of dilution is required for relief under the act.” Federal Trademark Dilution Act entails the factors that determine whether a mark is distinctive and famous. The act defines “dilution” as the “lessening of the capacity of a famous mark to identify and distinguish goods or services.” The FTDA answers that question, and the answer is no. This requirement

Yes the differences in the salts density will affect how much the salt floats. The dilution with the most salt will be the most dense. This is also buoyancy because the egg is floating in a liquid. I also thi9nk the one with the most volume will float the most. Did you know that saltwater is more dense than fresh water? The salt adds a

2. You have been asked to set up a dilution series, and then use spread plates to determine the viable cell count. Why is it necessary to use a dilution series when isolating bacteria from a biological sample using spread plating? [5 MARKS] It is vital to use a dilution series to reduce the concentration of the original biological sample so it is easier to count the number of isolated colonies which are present on the spread plate. The diluted samples will have a workable number of colonies on

of turkey though the dilution series explained above in the methods

and 1.0 mL of water, and 3.0 mL of dye and 0 mL of water. These samples were tested by the spectrophotometer, and the absorbencies recorded. This whole process was completed twice and the absorbencies were averaged. Lastly, final concentrations and dilution factors were calculated by using the appropriate formulas. The final portion of the lab consisted of creating a lined scatterplot in Microsoft Excel with the absorbencies from the standard curve data chart. The chart was created to display the linear

by sweeping the potential from +6.00 to -2.00 mV. The calibration curve couldn 't be plotted with the obtained voltammograms, therefore, the cocaine-benzoylecgonine antibody concentration has been raised to 0.05 µg/ml (10 fold more) and the tracer dilution ratio to 1:10000. That leads to increase the absorbance (OD) detected by ELISA to 4. The obtained voltammograms were investigated and the calibration curve was plotted. It showed non linear four parameter logistic relationship fit between the concentration

specific gravity and density of sodium chloride of known concentrations. This lab required us to prepare a stock solution and use that stock solution for three dilutions. Each dilution had a different molarity because of the end volume. The first diluted solution had a concentration of 0.3107 M and a density of 1.0081 g/mL. Out of all the dilutions this was the lowest concentrations because it had to most water added to the stock solution. The second diluted solution had a concentration of 0.6213 M and

When testing one organism, for example Mycobacterium tuberculosis, the dilution is prepared in agar slopes but at this time it is necessary to prepare another identical set to be inoculated with the organism which is control. To make dilution a small volume of water is used and then the dilute is added to agar that melted and then cooled to 60degrees C. If chocolate agar is required blood is added, and

or absence of biological molecules in serum 2216. If the concentration in each test tube of the dilutions carried out will be more concentrated then the concentration of the test tube before it, then the color will be at an equal concentration with the other dilutions performed. The hypothesis was wrong because of the difference in concentrations due to the different measurements within the dilutions done. The test for starch was to add a drop of iodine solution to the pipette in the spotting tile

12-354-cv, decided on November 15, 2013. The Starbucks Corporation and Brand LLC went to appeal from a judgment of the United States District Court for the Southern District of New York, after being denied an injunction under the Federal Trademark Dilution Act of 1995. This would prohibit Wolfe’s Borough Coffee from supplying Black Bear Micro Roastery their sub-company using “Mister Charbucks”, “Mr. Charbucks”, and “Charbucks Blend.” After an initial bench trial the District Court concluded that Starbucks

Thesis statement: The integration of indigenous music with Hip Hop and R&B not only promotes cultural diversity and allows for artistic experimentation but also raises concerns of cultural appropriation and dilution of traditional sounds. Supportive arguments: 1. Promotion of cultural diversity: The fusion of indigenous music with Hip Hop and R&B provides a platform for indigenous artists to express their cultural heritage and share it with a wider audience. By blending traditional indigenous sounds

pathogens. The experiment involved DNA extraction using silica columns and various buffers, followed by qPCR setup and analysis. Very precise procedures and protocols for biosafety measures and quality control, including technical replicates and dilutions, were used throughout the experiment. Results revealed concentrations of extracted DNA and provided insights into microbial dynamics. Despite challenges such as potential contamination during sample handling, the experiment showed the versatility

calibration, a dilution of the unknown sample would have to be prepared. Depending on how high out the range the sample reading was, the dilution would have to be made. After this the unknown would have to be measured again to see if the dilution of the sample made it fit in the linear range or not. If once again the sample was outside the linear range of calibration, then another dilution would have to be performed. The sample, then once again would have to be measured to make sure that the dilution worked

pineapple products tested is either in liquid or semi-solid form, stomaching is the most suitable way to make food homogenate(Andrews et al, 1977). Besides that, in this analysis process we used serial dilution method. Serial dilution is the repeated dilution of a solution to amplify the dilution factor quickly. It is commonly performed in experiments requiring highly dilute solutions with great accuracy such as those involving concentration curves on a logarithmic scale or involving experiments

Homeopathy was invented by a German physician, Christian Hahnemann (1755-1843). The idea behind his invention was his dissatisfaction with the medicine of his time. He used a small amount of cinchona tree bark containing quinine (drug used to treat malaria) to develop malaria symptoms. This led him to develop the first law of homeopathy, ‘let likes be cured by likes’. Homeopathy which is based on “like cures like” principle has remained the most controversial medical treatment in the world for a
