Chromatography in Biology
Chromatography is a widely used laboratory technique in biology for separating and analyzing mixtures of molecules. In the context of biology, it is often employed to separate and purify biomolecules like proteins, nucleic acids, and small molecules. Here's a brief overview:
Principle: Chromatography works on the principle of differential distribution of components between two phases: a stationary phase and a mobile phase. Components in a mixture will have different affinities for these phases, allowing them to be separated as the mobile phase moves over or through the stationary phase.
Types:
Paper Chromatography: Uses a strip of paper as the stationary phase. It's often used for the separation of pigments, amino acids, and other small molecules.
Thin Layer Chromatography (TLC): Utilizes a thin layer of stationary phase (usually silica gel or alumina) on a glass or plastic plate.
Column Chromatography: Involves a column packed with the stationary phase, through which the mobile phase (usually a solvent) is passed.

14:14 sir if we take one polar and one non polar then there will be no capillary movement,the capillary movement is due to the attraction of water and cellulose

[@Omidullah-ev9mn]

Very outstanding lectures dear sir ❤❤

[@AliAhmad-f5u2b]

Thank you ......sir ....out standing lecture..

[@BioChemWala]

Bundles of thanks

Nyce sir ji

[@BioChemWala]

Thanks

[@Zainabkhan-qr4km]

Sir plz agae or b topic k lecture dia kare

[@roshnakhan8837]

Poler kia hy or non poler kia hy

[@BioChemWala]

Polar means which have charge and vice versa

Sir G Tomorrow is " Sunday ". So kind ly upload 3 lectures because tomorrow is your holiday.
And don't say " I will try my best "🤣🤣.

[@WaleedManzoor-go2bd]

No lecture uploaded 😭😥😥😢😢

[@BioChemWala]

😭🤣😭

[@SabitGul]

What is the difference between centrifugation and chromatography?

[@BioChemWala]

See both lectures you will understand the difference

[@biomcqs904]

Weldon sir, where is yourbjob?

[@BioChemWala]

Still jobless 🥲

[@biomcqs904]

@@BioChemWala don't worry, your way of lecture is excellent. Hope you will get success in this line,

[@WaleedManzoor-go2bd]

Sir G Again ☹️☹️

Pehly waly video my ek point my mistake tha es lye.
