- please make sure final answer has correct sig figs Bovine serum albumin (BSA) has a molecular weight of 66.4 kDa and has an extinction coefficient of ?1% = 6.6. Calculate the concentration of BSA in solution if a sample has an absorbance of 1.35. The pathlength for the cuvette is 1 cm.Please help me answer and explain these questions: 1. Humans also express serum albumin. How do the predicted molar extinction coefficient and molecular mass of human and bovine serum albumin compare? 2. Which assay (A280 or Bradford) can sense lower concentrations of protein? What is the LOD for each assay?You need to prepare medium for your culture cells. Your salt solution is supplied at a 10X concentration but needs to be 2X for use. You also need to add fetal bovine serum for a final concentration of 8%. What would you add of each for the correct final concentrations in 5 L of media?

Place the following reactants in their proper order for the indirect ELISA test 1 = enzyme-linked antibody 2 = known antigen 3 = patient serum 4 = substrateWhat are the x and y values that you have input in the excel? I thought the x would be from the concentation and the y is from the A595 of sample minus A595 of blank but the linear equation that shows up in mine is different. It's y = 0.0443x + 0.0148.when testing unpasteurized milk you get a colony count of 118 colonies on plate A and 110 colonies on plate B after you plated .1 mL of a sample your .1 mL sample came from tube #6 you have prepared a serial dilution with six test tubes all tubes are a 1 to 10 dilution calculate the average CFU/ml of the original sample show work
