connected to a rubber tube and stopper was then placed in the beaker. The side of the glass tube not attached to the rubber tube is placed under the open end of the test tube. Next 10 ml of the 0.8% concentration of substrate solution was added to 10 ml of the phosphate buffer and placed into a 50 ml Erlenmeyer flask. The flask opening was sealed off using the stopper attached to the opposite end of the rubber tube. The concentration in the flask was swirled until 10 ml of oxygen was collected…

Ferrocyanide solution was made using 2.5 grams of Potassium Ferrocyanide and 125.0 milliliters of distilled water. The 2% Hydrochloric acid solution was created using 2.5 milliliters of Hydrochloric Acid and 122.5 milliliters of distilled water. The Potassium Ferrocyanide-Hydrochloric Acid Solution was prepared by mixing 125.0 milliliters of 2% Potassium Ferrocyanide and 125.0 milliliters of 2% Hydrochloric Acid. The Mix equal parts of 2% hydrochloric acid and 2% potassium ferrocyanide solution…

error in the measurement on the effect of pH on enzyme activity because the optimal pH of catalase is 7, not 10 because pH 7 is closer to the pH in the human body, where catalase normally functions. This error could have arose from ineffective buffers; the solution used was not actually that basic. Furthermore, there are errors in the measurements. There is some error in measuring the volume of gas because it is impossible to tell the instantaneous measurement of the gas level. This might have…

Fingernails As Trace Evidence Shamyiah Underwood Advance Criminalistics (FSC 620) National University Fingernails As Trace Evidence Trace evidence is the physical evidence resulting from the transfer of small quantities of material (e.g., hair, fibres, body fluids, textile samples, paint chips, glass fragments, gunshot residue particles, mud, insects, etc.) which may be collected by the police forensic unit, sexual assault team or medical examiner (Medical…

Grose, Natalie Krapcho and I’s project is titled “Concentration Quantification and Comparison with the HIC Eluate and Bacterial Lysate.” The overall objectives of this experiments include using a spectrophotometer to obtain absorbance of standard solutions to create a standard curve from this data, and subsequently using the equation of the curve to find the concentration of GFP elute which was purified from the column. Using the spectrophotometer to create a standard curve and running samples…

Arab Spring: riots, bloodshed, chaos. If you follow current events you’ll know that all over the middle east and northern Africa there is devastating turmoil. But, Northern Africa is far away from here, it has nothing to do with us right? Unfortunately this is not true. The initial cause of the revolts was food prices. The people were enraged in the sudden spike in the prices of food, and this is not an isolated incident. For instance, Syria experienced a destructive drought, and that same year…

First, adding 2ul of 5 times gDNA eraser, 3ul of DEPC water and 5 μl of RNA solution into PCR tube, then heated at 42 ° C for 3 minutes in an ABI PCR machine and then placed on ice for a while. Adding 2 μl of RT buffer, 1 μl of RT enzyme mix, 2 μl of RT primer and 5 μl of DEPC water into PCR tube, then heated to 42 ° C, 15 minutes, 95 ° C for 3 minutes and placed on ice for a 1 hr. cDNA was divided…

ABSTRACT Working with infectious agents that require BSL-3 level containment agents offers many challenges for researchers. BSL-3 containment laboratories are usually not equipped with expensive specialty equipment that is needed for studies such as flow cytometric analysis, microscopy, and proteomic analyses. Therefore, for most researchers that are working with BSL-3 level infectious agents, removal of samples from BSL-3 labs for these types of studies is necessary, and methods for complete…

(3µg) dNTP’s (10mM) antisense primers (5picomoles) and DTT (5mM) were added and denatured at 65oC for 5minutes. Then, the samples were plunged into ice. To this reaction mix, 50 Units of reverse transcriptase (MuMLV) and reverse transcription assay buffer (5X) was added and incubated at 30ºC for 5 minutes. First strand cDNA was synthesized at 42ºC for 60minutes. Thereafter, the abundance of the PMT members and HCT was studied using gene specific sense primers by qPCR (Light Cycler LC480, Roche…
