Serial dilution Essays

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

First part of this experiment was to create and plan out a dilution series to figure out the concentration of Salmonella enterica in the original solution. Three plates were labeled 1,2, and 3. Plate 1 being the most diluted mixture and 3 being the least diluted mixture. These plates were examined to figure out the CFU. The dilution factors of the samples were 1:30,000 for plate 1, the second plate was 1:60,000, and the third and final plate was 1:120,000. 100uL of each sample was pipetted onto the

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

Calculations Preparation of 1.5μmol/L mixed low-level standard dilution 150μmol/L × V1=1.5μmol/L × 10ml V1=(1.5μmol/L×10ml)/(150μmol/L)=0.1ml Conversion of milliliters to microliters (0.1ml×1000)μL= 100μL Preparation of 3μmol/L mixed low-level standard dilution 150μmol/L × V1=3μmol/L × 10ml V1=(3μmol/L×10ml)/(150μmol/L)=0.2ml Conversion of milliliters to microliters (0.2ml×1000)μL= 200μL Preparation of 3μmol/L mixed low-level standard dilution 150μmol/L × V1=7.5μmol/L × 10ml V1=(7.5μmol/L×10ml)/(150μmol/L)=0

In Tania Modleski’s “The Search for Tomorrow in Today’s Soap Operas” she introduces that the rare appearance and function of soap opera in two ways. The first being the viewer’s ability to occupy the text’s recommendation of the viewers position of ‘the good mother’, and the second using the stereotype ‘villainess’ to displace one’s own bottled up anger and powerlessness. I will analyze these two functions by using Modleski’s perspectives on the positions of soap operas, how a new genre of reality

melodramatic elements, but what is it specifically that makes both of these shows known as a classic example of TV melodrama? To best describe what makes a series like Knots Landing both a melodrama and a serial TV show we will look at two episodes.

Buffalo Bill, this nick name started as a joke in Kansas City Homicide. They said, “this one likes to skin his humps”. Bill is a cruel and crazy killer. He thought he was the transvestist, but he just immersed in his desire completely. He is greedy and vicious. I think it maybe vent his morbid and depress to the world. It is the result of lacking love in his childhood. He wants to be a woman, and search the maternal love from himself. He killed five women, and skin them to sew the cloth for himself

Little Red Riding Hoodie Once upon a time, but not so very long ago, I was the lead witness in a murder.

He terrorized the people of northern California during the late
