Rubisco Lab Techniques

Decent Essays
Intro

Rubisco is the most abundant protein on earth and is found in plants to aid the process of carbon fixation. Isolation of Rubisco from a mixture of protein allows it to perform at its optimal level because it has the highest purity. The three techniques used in this lab are salting out, Ion exchange, and SDS-page. After the last technique is carried out, Rubisco is in its purest form since purity is enhanced with each subsequent technique.

Salting out is the first isolation technique used in this lab. This technique requires an addition of ammonium sulfate into a solution containing a mixture of protein (Duong-Ly & Gabelli, 2014). Since Rubisco is negatively charged and the ammonium ion in water is positively charged, Rubisco and water

    The purpose of this lab experiment is to extract chromatin from an animal liver and strawberries. Unlike humans whom are diploid organisms with two sets of each chromosome, one from the mother and the other from the father, strawberries like most fruits are polyploidy, consisting of more than two copies of the same gene. Strawberries are octoploid that have eight copies of each gene, making it an ideal fruit for DNA extraction. Frozen strawberries are ideal because the ice in the intracellular fluid causes the cell to lyse and expand, destroying the cell and nucleus membrane of the cell. Strawberries are soft and easy to crush using a mortar and pestle.…

    Rubisco exists in four forms. Form I Rubisco is a hexadecamer, which is repeated four times in the basic structural motif, a dimer of large subunits, to form a catalytic core of L8, with small subunits on the top and bottom of this core (L8S8).14–16 Form II Rubisco is a simple dimer of large subunits, ranging from L2-8, sharing 25–30% identity to the L subunits of Form I Rubisco. This structure is similar to the structure of the basic dimer of the Form I Rubisco despite some differences in catalytic properties.16,17 Form III Rubisco is the dimers of large subunits in either an L2 or (L2)5 and is found only in archaea. Form IV Rubisco (Rubisco-like Protein) is a simple dimer of large subunits (L2) that do not use CO2 as a major carbon source.18,19…

    Bacteria cells are taken from the culture and literally stabbed into a gelatin medium using either an inoculating needle or loop. If the bacteria contains enzymes called proteases, the enzyme will break down the proteins found in the gelatin and will leave a liquid residue in the tube. If the bacteria contains no protease enzymes, no liquid will be formed and the gelatin media will appear unchanged. The bacteria tested created liquid in the tube which proved it was positive for the gelatin stab test and possessed the enzyme protease.…

    It is hypothesized that the optimum pH of trypsin is 8. Three different pH levels were tested, and each level consisted of three trials. The pH of 5 showed an average absorbance of 0.021±0.002, the pH of 8 showed an average absorbance of 0.167±0.030, and the pH of 11 showed an average absorbance of 0.088±0.001. Based on the standard deviation, there was a lack of variability between each trial for the pH levels of 5 and 11, yet the trials of the pH of 8 varied greatly compared to the other levels. The p-value between pH 5 and 8 was 0.0011 and the p-value between pH 8 and pH 11 was 0.0106.…

    Aim - The aim of this experiment is to find out at what age the ability to hear high frequencies begin to degrade. Hypothesis - As people get older the ability to hear high frequencies is much lower than the ability to hear high frequencies as a child. Background - As people get older, their capability to hear degrades whereas younger people like children, have a much better hearing since adults have experienced loud noises throughout their lives which degrades their hearing a little. The U.S department of health and Human services further explain that when a noise/sound/frequency is heard, the parts of the ear (inner, middle and outer ear)…

    Chromatography is a process used to separate molecules on the basis of chemical or physical properties, such as molecular mass, charge, or hydrophobicity. (Ninfa 121) There are many types of chromatography processes that can be used in different experiments and scenarios. These chromatography processes on include Gel filtration, ion exchange, and high pressure liquid chromatography. However, in this laboratory session the process of affinity chromatography is utilized to purify a His-tagged protein RNase H. The Separation of molecules that happen during affinity chromatography is based on specific interactions between an enzyme and an substrate.…

    The cell wall of a bacterial cell has many functions. Not only does it protect the interior of the cell from changes in its environment but it also helps give the cell shape. In bacterial cells, the cell wall helps prevent cytolysis due to an imbalance of water pressure between the inside and the outside of a cell. The cell wall also contributes to the pathogenicity of a species. As explained by our textbook, “the chemical composition of the cell wall helps to differentiate major types of bacteria”…

    To prepare the gel, students mixed .3g of agarose and 30mLs of 1X TAE buffer in a 125 ml flask (Penn State Biology 220W Lab Manual, pgs.55-59). The mixture was microwaved and set to cool for 3 minutes. After the cooling process, 1µl of ethidium bromide dye was added to the agarose. The mixture was then poured into the gel caster of the electrophoresis unit. Once the mixture formed a solid gel, 1X TAE buffer was poured over the electrophoresis unit.…
