Are we related? 👀

exactly that I'm Greek I study in Greek university and it s easier for me to learn all this in English than our notes that she gave us its not make sense she put so much useless details and they lost the mane subjects thanks for every one that really want to teach and not go to just do their job take the money and go

Because they have to pass the time

Many professors are researchers first and foremost, but I agree it’s definitely an issue. They may be excellent mentors and teachers to their grad student researchers, but when asked to explain basic principles of biology to a class of undergraduates, they often falter. This is because 1) professors do not receive formal training as educators at the K-12 levels do (absurd right?!) and 2) there is no incentive to go out and seek that training in their own time. Professors are made to wear many hats, and the most important and pressing one is obtaining grant money to fund their research. The good professors people have at university are often those who either did seek some sort of formal training during their PhD/postdoc or who just have a knack for presenting complex concepts. What’s that mean saying? “Those who can’t do, teach.” Well at university it’s the inverse: “Those who CAN do, [often] suck at teaching.” 😆

Don't ask yourself show it to your professors and ask them why can't you teach like this😂

Ahahahaha

Well, that´s nice to hear!

Amazing!

In many cases, because they were never really taught how to teach...

Microsoft Powerpoint

If the proteins are unfolded it is difficult to sort them accoriding to their size (in kD)... Why? Because some proteins may folded like a tightly packed ball whereas others have a longer structure... to make that equal unfolding is important. Apart from that, the unfolding is essential to mask the charges (this would not be possible when they are tightly packed).

This is the case for a galvanic cell it is reversed in electrophoresis, the positive pole is the anode. It is confusing but below is the explanation. In a galvanic cell, the anode is (-), and the focus is on pushing away electrons from the anode to supply power. In an electrolytic cell and gel electrophoresis, the anode is (+) and the focus is on attracting the negative ions in solution from inputted power.

"the equal mass to charge ratio"

This technique is part of another method that can be used for that: Immunoprecipitation... you direct an antibody against the protein of interest (want to find out the interaction partners of that protein)... you isolate this protein and everything that is binding to it. Then you can run SDS PAGE to see the size of the proteins you have pulled down with your target.

@@henrikslab thank you so much for your explanation!

Usually, for SDS one uses the TRIS-GLYCIN BUFFER: It contains Tris, Glycin and SDS (0.1%)

@@henrikslab and u didnt mention about bromophenol blue..glycerol..gel preparation...or is there any another video?can u help me?

würde Sinn machen, es gibt nämlich kein vernünftiges Vid auf deutsch

In der Wissenschaft sollte man aber schon Englisch können ^^

Sei doch froh dass du gleich bisschen scientific English lernst. Hilft auf jeden Fall wenn du mal vorhast papers zu lesen.
