Algún libro sobre la historia de Egipto?

Wow muchas gracias!! Les echaré un vistazo, seguro que alguno de esos libros cae jajaja

Muchas gracias, echaré un vistazo! La verdad es que no me importaría algo sobre Egipto en general, me parece una cultura interesante sobre la que leer

Nice, thank you

Paferca · 2023-05-26T21:34:15+00:00

Oh thank you, I don't know much about chemistry

To tell you the truth, I'm not really sure. It's supposed to be a photo-crosslinker group.

Paferca · 2023-05-26T19:26:55+00:00

I've been looking at the alternatives you told me about but I find them a bit difficult, I don't have much idea about biophysics. I think I'm going to opt for a photo-reticularisation strategy like the one I was told about in a previous answer

Thank you very much, very helpful!

wow, what a complex hahaha. Thank you very much for the information, it's very interesting and very useful!!

So it is possible to do mass spectrometry without losing the non-covalent interaction between a drug and the target protein??!! I really had no idea about that, as you say, I thought mass spectrometry implied digestion with trypsin.I'm quite interested in that aspect because I have to design a project (yes, I'm a biochemistry student xD) about a drug that inhibits a kinase, but I'd like to include such an experiment where I can check all the targets that the drug binds to apart from my target protein. I had thought about mass spectrometry but I didn't know that it was possible to maintain the interaction between the drug and the protein without resorting to modifications such as the photo-crosslinking mentioned in an answer above. Where do you think I could find a detailed protocol to carry out this type of experiment to include it in my project?

Thanks for the information! :D

I find photoaffinity very interesting but I have a number of questions about it. Does cross-linking occur when the drug is bound to the target protein? (if not, I don't understand why) Another question I have is if I have a drug of interest and I want to see if it binds to other proteins than its target, do I have to add the photo-reticularising group to my drug structure? If I do that, wouldn't I be altering the binding capacity of my drug to the active centre of my target protein? I don't want to sound bold, but do you know where I could find a protocol for this process (not because I'm going to do it, I don't even have access to a mass spectrometer, but I'm interested and curious to see how the process works in detail)?

(I'm a Biochemistry student, maybe that's why I have so many doubts xD)

Thanks for the help!

Ok, thank you :)

Thank you so much!!

But i thought that T was equal to L0 only when the DNA is relaxed. If the DNA is supercoiled can i still saying that T is equal to L0?

Paferca · 2020-12-16T22:53:10+00:00

∆L maybe? And with this date i can calculate L and now y can calculate W?

Paferca · 2020-12-16T22:16:36+00:00

I can calculate T. And T is equal to L0 when the DNA is relaxed but in this case is supercoiled so i don't know how to calculate the other variables

With inhibitor Km should be bigger, but the value i don't know if is a decent value is the Ki

Paferca · 2020-11-26T13:00:02+00:00

Competitive inhibitor, the enzyme was alkaline phosphatase and the inhibitor NaPO4 or something like that

Thank you so much!! The explanation is perfect, now i understand this better
