    ELISA (Enzyme-Linked Immunosorbent Assay) ELISA is a technique to detect and quantify substances like proteins, antibodies, and hormones. The target antigen is immobilized to the bottom of the well and then an antigen-specific detection antibody is added. The detection antibody makes it possible to measure results. The three most common formats of ELISA would be direct assay, indirect assay, and sandwich assay. In direct assay, the antigen immobilizes to the bottom of the well where a labeled antibody attaches to it. In indirect assay, the the antigen immobilizes to the bottom of the well and then a primary antibody binds to the antigen. After that, the labeled secondary antibody binds to the primary antibody. In sandwich assay, a pre-coated…

    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…

    Skill #28 Kirstin Krueger #21839116 ELISA is an abbreviation for "enzyme-linked immunosorbent assay." An ELISA test uses different parts of the immune system, different antibodies, and color changes to detect immune responses in the body. CPLi, or Canine Pancreatic Lipase Immunoreactivity, is a specific lipase that is only found in canine pancreatic tissues. The CPLi ELISA snap test is made by Idexx and is used to measure the concentrations of pancreatic lipase in the serum of the patient.…

    determine the cell number. Finally, to quantify the cell number by stander curves, the optical density were plotting with the known cell numbers using linear stander curves. The cell numbers was adjusted by interpolating from a stander curve using prism software (R2=0.98). 4.2.3 Hormone analysis 4.2.3.1 Progesterone ELISA Analysis of progesterone in GCs supernatant is done by enzyme linked immunosorbent assay (ELISA). The assay was performed as described in section 3.2.2.2. P4 concentrations…

    Griess reagent (Sigma-Aldrich Chemical Co.). For this assay, the supernatant was collected and mixed with the same volume of Griess reagent for 10 min at room temperature in the dark. The absorbance was measured at 540 nm using a microplate reader, and NO concentrations were calculated by referencing a standard curve generated from the known concentrations of sodium nitrite [Lee et al., 2015]. Measurement of PGE2, TNF-α, and IL-1β production in RAW 264.7 macrophages To measure the production…
