What Is The Functional Relationship Between Albert And Alice

Amazing Essays
In this research paper, the functional relationship between protein named Albert and Alice will be prove using two advance techniques. Most of the molecular processes within the cell are carried out by protein-protein interaction (PPI), diseases such as cancer, Alzheimer’s disease can caused by abnormal PPI. As prior knowledge has advocate that this two proteins may have similar cellular pathway, therefore understanding if they have PPI becomes vital.
There will be two methods described in this paper, Enzyme-Linked immunosorbent assay (ELISA) and proximity ligation assay (PLA). ELISA are reported by Wisdom,G. B. (1976) to be more sensitive than quantitative precipitation, immunofluorescence, agglutination, passive hem agglutination and complement

The purpose of this method is to wash away any excess protein that does not bind to the plates.
PLA method
The method is adapted from Söderberg et al’s (2008) research papers. Proximity ligation assay often contains four major part, 1) PLA probes, 2) Ligation, 3) Amplification and 4) Preparation for imaging. The steps are shown below
1. PLA probes: Wash the well with PBT for 10 minutes for 3 times, incubate the PLA probes for 2 hours at 37 degree C.
2. Ligation: Wash the body walls with wash buffer A twice for 5 minutes each, incubate with ligation solution
3. Amplification: Wash the body walls with wash buffer A twice for 2 minutes each, incubate with amplification solution for 2 hours at 37 degree C.
4. Imaging: Wash the well with wash buffer B twice for 10 minutes each, wash with 0.01x wash buffer B once for 1 minute, equilibrate in a few drops of mounting solution for at least 30 minutes before mounting, or store overnight at 4 degree C, using fine forceps, transfer the body cell on a platform. Position the body walls in rows and in the same orientation within a drop of mountant, place coverslip, seal the slide with clear nail polish, and store the slide in the dark at -20 degree C until ready for confocal

    The entire (500 µl) mixture was pipetted onto a purification column and spun for 2 minutes in the centrifuge. The filtered waste was disposed of and the column was placed into the tube. 500 µl of wash buffer was added to the column then spun in the centrifuge for another two minutes and the waste was put in the waste container. This washing procedure was repeated once more. After tossing the waste on the second cycle, the column was spun to dry and then transfer to a clean tube labelled with the date and Thread or DRP1.…

    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 beaker was selected and labeled as resolving gel solution.…

    Incubate the bottles for 5 minutes. Swirl the bottle around to make sure that trypsin removes all the cells from the bottle. Then, use a pipette to remove the substrate from the bottles and into centrifuge tubes. Then centrifuge the tubes for 1 minute at 1000xg. Make sure that the centrifuge tubes are properly balanced.…

    Initially coarse aggregate, fine aggregate, cement, fly ash, and GGBS were dry mixed for three minutes in the mixer. After dry mixing, alkaline activator solution was added to the dry mix and wet mix was done for 4 minutes. Finally, extra water along with super plasticizer was added. The mixing of total mass was continued until the binding paste covered all the aggregates and mixture become homogeneous and uniform in color. The fresh geopolymer concrete was used to cast cubes of size 150x150x150mm to determine its compressive strength.…

    A stir bar was added into the flask containing isoborneol, and the flask was attached to a ring stand to rest on top of a magnetic stirrer device. In consistent drops, 0.63 mL of glacial acetic was added and the reaction had a pH of 2, which was measured with pH indicator paper. Then, 0.50 mL of 10% w/v sodium hypochlorite (NaOCl) solution was added, and the reagents were reacted for three minutes. Shortly after, 5.13 mL of 10% w/v NaOCl was added incrementally with a Pasteur pipet for about ten minutes. A thermocouple was periodically placed on the outside of the flask to make sure that the mixture did not reach past 50 °C.…

    The jar was then placed at 37 ⁰C for 96 h. For each retting, 100 g dry bast samples (replicate 4) was placed in 9 L plastic tanks. The fiber ratio and water was 1:50 and left for 7 days at 30 ⁰C. For chemical retting, 2% of NaOH solution was prepared. Bast sample and NaOH were placed in glass container airtight and boiled in water for 2 h. The retted fibers were then washed with cold water and dried. The fiber were combed using special comb in order to separate the long fibers for quality assessment.…

    Before hatching, the Artemia’s cysts will be sterilized by immersing 200 ppm sodium hypochlorite for 20 minutes. The sterilized cysts will be poured into a fine steel mesh coffee filter and rinsed 3 times with seawater. Then cyst will be transferred to the prepared Artemia tank whereupon they will be hatched after 12 to 24 hours. This tank will be used exclusively as nauplii nursery and will maintain throughout the food chain experiment as a food source for juvenile Artemia for the 3 treatment tanks. Once the nauplii reach approximately 1 mm in length (about 3 to 4 days), water will be drained out using filters and about 100 ml of the concentrated nauplii will be collected and feed with appropriate algae source in 2 tanks.…

    The cells were centrifuged for two minutes at maximum speed. Once centrifugation is completed the supernatant was removed and 250 microliters of re-suspension (R3) was added to the remaining bacterial pellet. This was then re-suspended using a pipet, until homogeneous. Then 250 microliters of lysis solution was added. This solution contains SDS detergent, which dissolves the cell membrane and denatures proteins.…

    Sample is slowly and carefully placed on the mixture to avoid air bubbles. Sample is clamped for 24 hours to allow it to stick. Sample is removed and is now grinded down to 30 m to become translucent and therefore become visible under microscope. 5.2.2 Preparation of a dyed sample Sample is cleaned and cut into a square of size 2X2 cm. Dye is prepared using 95 mg epoxy Resin, 0.3 mg blue Dye, 12.5 ml thickener, 12.5 ml thinner Epoxy and hardener mixture is prepared (used to glue samples to the glass slides).…
