Suppose you were instructed to repeat this experiment, again using equine albumin antiserum in two tubes. You layer equine serum (containing equine albumin) over the antiserum in one tube and pig serum (containing pig albumin) over the antiserum in the other tube. After incubation, you see precipitous rings in both tubes. Explain these results. Is this due to poor specificity or sensitivity of the test?
Following is the data and notice that it is a terrible idea to culture hMSCs longer than 10 days.

The trial involves grafting hMSCs intopatients suffering from interveterbral disc disease using a degradable polymer scaffold. You are going to 3Dprint a porous cylindrical scaffold that is 2 cm in radius and 1 cm in height (matching the dimensions of adegenerated disc). Assume a porosity of 50%. You will fill available volume of the scaffold with hMSCs at adensity of 1 million cells per cm3. Based on the data above, what starting number of cells will you use andhow long will it take you to get enough cells for the trial? Part2The trial is a failure (patients did not report any reduction in back pain). Your team wants to try againusing 85% hMSCs and 15% nucleus pulposus cells .…
At the station there is a 2 mL microcentrifuge tube containing sheep blood and 3 tubes containing the following solutions: 0 mM, 300 mM, 600 mM of sucrose. The tubes are randomly labelled A, B, C. 2 mL of each solution were transferred to a different microcentrifuge tube, 20 ul of blood were then added to each tube, and they were mixed well by inverting the tube for multiple times. They were observed and it was determined whether the solution in each tube was hypotonic (Yes or No) relative to the blood cells. In addition, the solutions were diluted with water to help you determine which solution is which sucrose concentration. What sucrose concentration corresponds with each tube? Tube Hypotonic (Yes/No) Hypotonic after 1:1 dilution with water (Yes/No) Most likely Sucrose concentration (mM) A No Yes B Yes Yes C No No
We need to prepare a stock solution of medium for your culture cells, which usually includes liquid salt solution and bovine serum. Our liquid salt solution is supplied in a 50X concentration, and we need to dilute it to 1X for use. We also need to add 75% fetal bovine serum for a final concentration of 15%. How would we make up 0.80 liters of this culture media using water as our solvent?

HBs Antibody Principle: This test uses the “sandwich principle”, a slide phase colloidal gold enhanced immunoassay technique for determination of HBs antibody in human serum or plasma. The nitrocellulose membrane was immobilized with HBs antigen on the test band region and anti-HBsAg antibody on the control band region. During the assay, the specimen is allowed to react with the colored conjugate (HBs Ag colloid gold conjugate); the mixture then migrates chromatographically on the membrane by the capillary action. For a positive result, a color band with the specific antibody-HBsAg complex will form on the membrane. Absence of this colored band in the test band region suggests a negative result. To serve as a procedural control, a colored band at control region always appears in the test area. The reagent contains scavenge antibodies to reduce nonspecific reactivity in human serum or plasma specimens. The sensitivity of the test is 10mIU. HBs Antigen Principle:…
Please asap. thankyou. The following diagram represents the results of hemoglobin samples of 5 patients (1-5) that were run on an electrophoresis gel at pH 9.2. The first 3 lanes show the control samples, for comparison. Using only the letters "AA" "AS" and "SS", fill in the blanks below indicating the most likely genotype of each patient, based on these protein electrophoresis results.

Recombinant Protein G from Streptococcus are covalently attached in an oriented fashion to magnetic beads. Bovine Serum is added and the antibodies are captured by the beads. Using the magnetic device, beads are attached and unbound material is washed away. Antibodies are eluted using a lower pH buffer and the solution is neutralized. The equilibration step is adding the serum sample to the buffer-equilibrated (pH 6) magnetic Protein G beads. What was expected to occur if this step was missed? When we mix the samples on the mixer, it was crucial that there was no foam present in the sample - why is this and what part of the mixture would be "foamy" at this step? Lastly, we use an neutralizing buffer after eluting the samples from the column. Why is this step important?
A COVID-19 test, which produce result in 10 minutes, has the following test characteristics. The test has a 95% sensitivity and a 95% specificity. The State of Massachusetts is in dilemma whether to test symptomatic individuals or the entire residents to decrease the spread of infection as depicted in the following two scenarios. Scenario A. The State of Massachusetts wants to administer the test on 40,000 individuals who will develop cough, fever and shortness of breath in the next 10 days to identify COVID-19 infected individuals and institute public health measures. The estimated prevalence of COVID-19 in this population is 750 per 1,000 population using a gold-standard test. Scenario B. The State of Massachusetts wants to administer the test to its entire COVID-19 uninfected population (6,750,000). The estimated prevalence of COVID-19 in this population is 5 per 1,000 population using a gold-standard test. Please help the State of Massachusetts by responding to the…
