Why is EGTA used in a CaM agarose pull down assay?
Why will there be no binding of gene with CaM in EGTA solution?
1.EGTA is chelating agent which binds to calcium ions and chelate it with high affinity so it used to analyze whether the target protein is calcium dependent or independent
2. Only specific target protein binds to calmodin (CaM) in presence of calcium in EGTA solution. Gene will not bind.

The pull down assay described in Tutorial 7 is similar to co-immunoprecipitation technique described earlier in this course. Which of the following are differences between the IP/co-IP techniques and the pull down assay? Select all that apply. The co-IP assay utilizes antibody specific to the target protein. The pull down assay is used to study protein-protein interactions. O A pull down assay enables researchers to test the binding affinity of protein fragments The detection method used is different, co-IPs use...
A graduate student has performed an in vitro pull-down assay to determine whether two proteins, Protein A and Protein B, interact with each other. Protein A is known to be 35 kDa and Protein B is 60 kDa. To determine whether there is an interaction the graduate student runs the sample down an SDS-PAGE gel, which is later stained with instablue dye. Unfortunately, the SDS, found in both the lysis buffer and SDS-PAGE gel, has expired (and is no longer...

What is the reason why microbiologist use a apoptosis assay? What are Apoptosis Assay used for in the microbio world? research wise is it use for cancer reasearch etc. Give details please.
In plaque assay, why is soft agar used in the top layer? Why is it important that bacterial cells should be in the exponential phase for this experiment?
Could a plaque assay be used to detect a change in viral quantities like TCID50 assay can. Why or why not?
3. Why can we assume in the Biuret assay that BSA (used in the standards) and casein (our protein of unknown concentration) give about the same amount of A550 per mg? 4. To calibrate the Ninhydrin assay, glycine was used. Draw the structures of Glycine, Arginine, and Threonine. Instead of glycine, would it be acceptable to use Arginine or Threonine? Explain!
We are used to using a 1.5% agarose solution, so if the solution is 1%, would a longer band or shorter band move faster in gel electrophoresis?
Define CAM. List and describe 3 different types of CAM available today. Why are these therapies not used more widely in medicine today? How would you educate your patient if they wanted to choose CAM alternatives to their treatment? Please provide at least a three paragraph summary for your answer
Why can’t phosphate buffers be used in the assay done in this prac?(Enzyme kinetics) Which type of inhibitor binds just to the ES complex?
