partners. To begin with the experiment, the gel caster was assembled. The two plates were properly cleaned and then introduced well align to avoid leakages to the plastic platform. Once there were correctly adjusted. A wash bottle was used to pour water to the edges and wait for about 5 minutes to verify there was no leakage. The TA came to the group in order to verify the correct assembly. Then, the water was through on the sink. 40 ml of 15% resolving gel solution was prepared. A 100 ml…

using agarose gel electrophoresis. Species identification was performed by importing finalized CO1 sequences into two DNA databases to ensure accurate identification. Phylogenic analysis was then conducted to determine relationships between identified species. Electrophoresis Electrophoresis of DNA run in 2% agarose gel showed successful extraction of DNA in samples 1-8, 12 and 14-16. Samples were of good quality with high molecular weights (Figure 2). Samples 11 and 13 in Row 1 of gel 2 were…

samples is Gel Electrophoresis (GE). Overview of Gel Electrophoresis: Gel electrophoresis is an effective and widely used method that separates and identifies molecules on the basis of electrical charge and size. GE is a particularly useful method for separating amino acids, which are charged, organic molecules such as DNA (deoxyribonucleic acids), RNA (ribonucleic acids), and proteins.…

Sweta Soni 2/22/15 Biochem Lab Experiment 5 Introduction The purpose of Experiment 5-1 is to separate a mixture of three molecules—blue dextran, cytochrome c, and potassium chromate—through the use of gel-filtration chromatography. The volume at which each molecule elutes will be recorded in order to determine the accuracy of separation. The purpose of Experiment 5-2 is to purify the E. coli enzyme, β-Galactosidase through the use of affinity chromatography on…

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.…

What is silica gel New shoes, Pill bottles, Beef jerky, New purse, new backpacks. Silica gel is the little packages inside of products that were listed . Silica gel is to keep moisture out of those objects. Silica gel keeps the moisture from the product so it can stay dry. Silica gel can be in numerous places they can be even bought online. What does silica gel do Little packs of silica are(desiccant) means is a drying agent something that drys objects and absorbs the the moisture…

cutting up the dsDNA into smaller fragments, they usually undergo electrophoresis so data can be obtained. Small quantities of nucleic acid can be detected through agarose gel electrophoresis. Samples with the desired plasmid, DNA loading dye, restriction enzymes, and water are mixed and carefully pipetted into wells on an agarose gel. There will also be a well with a DNA marker to help determine the relative sizes of the fragments. A…

It was found to be an adsorbent of vapor and gases in canisters. The method of producing silica gel was patented in 1918 by Walter A. Patrick , a chemical professor at John Hopkins University. 2.2.2 SYNTHESIS OF SILICA GEL 2.2.2. a) USING KAOLIN BY-PRODUCT The synthesis process (D. Brahmia 2014) was carried out in two steps namely, (1)Metasilicate sol preparation and (2) Metasilicate destabilization…

Gel beads are present on a column and, as the mixture (in this case liposomes) flows through the column, aspects of the mixture can be trapped via binding to, or entering, the gel beads. This occurs on a size related basis, with molecules of specific size being entrapped by the column (Ruysschaert et al., 2005). In the case of liposomes, their large size causes them to be entrapped between the gel beads (lots of gel must be present to stall the liposomes for…

Abstract This experiment involved an electrophilic aromatic substitution of bromobenzene. Two products were formed: 4-nitrobromobenzene (4-NBB) and 2-nitrobromobenzene (2-NBB). Utilizing column chromatography and recrystallization, separation and purification of the two products was obtained. The mass of 4-NBB, the para product, was 1.57 grams, while the mass of 2-NBB, the ortho product, was 0.80 grams. The para product was expected to have the higher yield, since it is more stable and…
