  • Dna Gel Electrophoresis

    under such condition. Another reason could be that the cell did not get enough heat shock, or not enough pre-incubation time with CaCl2, which means the bacterial cell wall was not permeable enough for the DNA to come inside and interact with the bacterial DNA. The DNA gel electrophoresis showed that there were no fragments…

  • Difference Between Pcr And Gel Electrophoresis

    RESULTS Transformation: the transformation of the ade2 gene to the kanamycin resistant gene (ade2::kan2R) cause the cell to become red and grow on mediums containing G418 or kanamycin resistant mediums was observed to have occurred. PCR and Gel Electrophoresis: Figure 1 is the product of gel electrophoresis containing the wild type and transformed PCR products, either being or not being cut by HindIII. From the left (reader’s left) of the gel to the right the lanes are; 1.Ladder, 2. transformed…

  • Essay On Agarose Gel Electrophoresis

    Background DNA molecules can be too big to analyze through electrophoresis, some they must be cut up into smaller pieces. In order to cleave dsDNA at the specific sites, making sure each fragment contain the desired sequence, restriction enzymes are used. Restriction enzymes can recognize a specific sequence of nucleotide and hydrolyze the bond of the DNA backbone. Hence, the fragments from the same DNA source will also be the same if cleave by the same restriction enzymes. Restriction enzymes…

  • Vaccine Analysis Case

    Discussion When comparing the banding patterns of the crime scene to those of the suspects, the resulting gel indicates that Suspect 2 was at the scene of the crime. Although enzyme 1 produced identical DNA fragments across the gel, enzyme 2 did not. This is evident in lane D and possibly indicates that this enzyme was unable to bind to recognition sites similar to the crime scene DNA in well B. Thus, it produced a DNA fragment smaller in size that travelled further. Since the DNA evidence in…

  • Denaturation Of Proteins Lab Report

    Denaturing Protein Gels Kaytlin Goodwin Cedarville University Introduction Electrophoresis experiments are conducted on proteins for the purpose of separating proteins based on their characteristics. The characteristics that can be examined during the experiment are dependent on the preparation of both the proteins and the gel medium through which they will run. Native gel electrophoresis experiments highlight and examine multiple protein characteristics, such as size, charge, and…

  • Gel Electrophoresis Lab Report

    Gel electrophoresis is a method used for separation and analysis of molecules such as DNA, RNA, and proteins, based on their sizes and polarity. DNA (deoxyribonucleic acid) is a molecule that carries most of our genetic information, and possesses a negative charge. During gel electrophoresis, DNA fragments can migrate through the gel also known as agarose when placed in a powerful electrical field. The rate at which the DNA fragments will move through the gel depends on their relative size.…

  • Protein Analysis Lab Report

    In this experiment, a SDS-PAGE gel was used to analyze the protein samples from the MBP-AP and WT-AP experiments. The samples are then referenced to the ladder to determine the molecular weight of the MBP-AP and WT-AP proteins. Then the UV absorbance of the two proteins from 240 nm to 340 nm is determined using a nanovolume cuvette. The absorbance at 280 nm was then used in conjunction with data from previous experiments to determine the concentration of the MBP-AP and WT-AP protein samples.…

  • Mixed Protein Solution For Pancreatic Cancer

    respectively, and combined into one solution. The resulting solution will then be subjected to 2-dimensional gel electrophoresis. This will be done by transferring the mixed protein solution to isoelectric tube gel (pH 3-10) and subjecting it to a constant electric current (145mA). After the gel has been allowed to run for about an hour, the isoelectric tube will be rinsed with running buffer and set aside. Next, an SDS gel will be prepared in order to separate the proteins based on mass. This…

  • Bovine Serum Albumin Case Study

    Bovine serum albumin (BSA) is usually used for generation of nanoparticles (NPs) in drug delivery systems. This paper presents a study on the simple coacervation method for fabrication of BSA nanoparticles.An artificial neural network (ANN) model was developed to predict the diameter of nanoparticles based on experimental data. Effect of pH, temperature, initial BSA and cross linker concentration, molar ratio of BSA to ethanol, agitation rate and rate of ethanol addition were investigated on the…

  • Human DNA Fingerprinting

    fingerprinting, is a DNA pattern that has a unique sequence such that it can be distinguished from the DNA patterns of other individual. The two major uses for the information is for personal identification and for the determination of paternity. DNA can be analyzed from a variety of human samples including blood, semen, saliva, urine, hair, buccal (cheek cells), tissues, or bones. The polymerase chain reaction (PCR) is used to amplify the genomic DNA from a sample and electrophoresis is used…
