Biophysics enzyme experiments for a second year lab

AI Thread Summary
The discussion focuses on finding suitable enzyme and molecular motor experiments for second-year biophysics students. One suggested experiment involves observing cell locomotion on Saran Wrap, where the movement of cells can be visualized through the wrinkling of the material, allowing for calculations related to the actin-myosin system. The conversation also highlights the importance of understanding the available laboratory instrumentation and the students' level of experience in wet chemistry. An alternative experiment proposed is immunostaining for actin or tubulin, which combines chemistry, biology, and optics. Overall, the thread emphasizes the need for accessible and educational experiments in a biophysics lab setting.

Hi

I hope I'm posting this in the right section. I am trying to find some experiments that would be appropriate for an introductory biophysics course for some second year students. Any links/pointers in the right direction would be great, although I'm specifically looking for enzyme/molecular motor experiments. I thought there would be many of these experiments on the web or in books but at this stage I am struggling to find any.

Thanks in advance for any help

Here's an idea off the top of my head- one of the first papers on cell locomotion involved cells deposited on Saran Wrap. As the cell created filipodia and began to move, the saran wrap became wrinkled and easily visualized. From this, the author (IIRC) calculated the forces involved for cell locomotion (which involves the actin-myosin system). I could try and locate the paper (it was in Science in the 70's, I think), but you need a lot of equipment to be able to do this: cell culture specifically.

Actually, that's a better point- what type of laboratory instrumentation do you have access to? What level of wet chem lab sophistication do the students have?

A simpler experiment could simply be immunostaining for actin or tubulin (or both): some good chem experience, some bio experience, some optics experience.
 
That experiment sounds very cool, thanks for your reply. I'll have a further look into that. I'm not 100% sure on how sophisticated the lab is at this stage, but I assume we will head to the biochem lab to do some of the experiments.
 
comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
