1. Briefly describe the principles behind the Bradford protein assay, describing the weaknesses andstrengths.2. What were the differences seen between the two analysis methods (paper vs. excel) and thecurve from the De-Novix DX-11+ instrument.
Insulin binding to an insulin receptor of a cell stimulates…
Insulin binding to an insulin receptor of a cell stimulates tyrosine kinase activity. However, uncontrollably high number of insulin-insulin receptor binding causes negative impacts on cellular viability. A researcher developed a new ligand X that can act as a scavenger of the insulin by binding to an insulin receptor. Researchers find that if given enough […]
