Nice demostration man! <3
This is so easy to understand, well explained and well demonstrated.
Thanks man i have exactly that one adnd was wondering
Why osciloscope shows same signal when different buttons pressed on remote control?
Thank you, you made my day 😊😊
😮😮
Commandment #1: Thou Shalt Not Dump Organic Solvents Down the Sink -- that is a very wise rule to follow!
❤ EXCELLENT VIDEO THANK YOU FOR SHARING 🇺🇸
Thank you!
Acid = 48 kuning, 85 pink 3:42
Naoh + unbuffered = a drop or greenish color 2 drops for purple
naoh + buffer = 4 drops for orange, 15 yellow, 140 green, 150 purple >>> 200 drops great purple 5:43
adding capsul for buffer 1:08
unbuffered+ HCl a drop
❤
Thank you for explaining this, and doing what my bio prof should have done properly when assigning us this! I didn't have any idea how to interpret my gel. -_-
Excellent video! Thank you!
You don't know how hold a cuvette
❤❤
what buffer solution have you used?
Dumbest invention for sterilizing equipments ever... have to wastes soo much time
Thanks sir
Need one on how to make a syringe
Way cool oscilloscope....trying to get one from testequipmentdepot....guess a probe is extra.
Caw Caw!
how about writng catalysts on the arrow?
Hey Steve! Amazing video! Suoer clear and informative. This is exactly what I was looking for! I'm starting a new role in peptide synthesis 😊
Excellent. It worked superb. Thanks

بسیار عالی❤❤
This man should not be teaching children. He comes across as very arrogant, bossy, rude, know it all, superior and frightening attitude, my way or no way, assuming, disciplinarian, and little knowledge transferred. When you scare and frighten children you will do more harm than good. Science is not easy for all and should be fun, enjoyable, explained so that each child will feel they learned something and want to come back - not afraid to come back from not doing something "your way".
If my blank (sample buffer) is a colored media then how should I measure?
Thank you.please how many gram of siluca gel to sample
Is there any cheaper alternative for DEAE sepharose
Nice Explaination. Thank you.
Neeru ma'am bought me here.
What is the column you are using? Thank you.
Thank you very much for making this video! My professor expects me to do the same thing and here I am watching this❤
Hii there, nice video. I am bit confused on my synthesis as I got a sequence using phage display library against a pathogen for example: STFSQNG (N to C) and I want to synthesise it using Fmoc SPPS. But as the FMOC SPPS using Rink amide resins generate from C to N, should I use Glycine as first amino acid (reverse) or use S (serine) as first amino acid and then T,F,S etc.
Hi, I used sephadex G25 and packed the column similar to what's shown in the video. However, fluorescein doesn't retain as in the video but travels right though. Do you apply pressure in packing the column?
Please do a video on how to prepare culture media
Thanks alot ... this was very helpful
I told my girlfriend the same thing she didnt believe me at first.
the resistors leads and IR receiver leads connections are not clear. can you put a schematic?
Thank you so much for such an informative video! I have a PhD in Chemistry (but in solid state chemistry) and have recently switched to a new role where i will need to do some peptide synthesis and this video is absolutely amazing for me!
Very helpful 😊thanks
Hi, what is the size of the nitrogen tank? Best regards, Yasmin
Also in carbetocine the colour of Peptide is red during TFA cleavage deprotection
Hi Steve, will we use Kaiser test for deprotection
Thank you for that clear explanation, easy to understand and follow 👌
Thank you for sharing useful information and your demo was clear and to the point. Thanks from Jawaharlal Bharat INDIA 🙏
I gave do say your duuuuuuuuuuu was a very nice sine wave, well done.
s it possible to separate the sizes of DNA?
Comprehensive and clear explanation. Thank you
