SMRT | Single Molecule Real Time sequencing
SMRT sequencing stands for single molecule real time sequencing.
It is a unique sequencing method, that uses zero mode wave guide for sequencing process. Zero mode wave guide (ZMW) is a phenomenon in which light traveling through a pin hole (having diameter less than the wavelength of light) fails to pass through the pin hole. However some portion of electromagnetic energy still exist in small volume near the pin hole. This is known as Zero mode wave-guide. For sequencing purpose the DNA polymerase is immobilized on glass surface near the pin hole. The nucleotides are attached with fluorescence probe. Only those nucleotides that comes under zero mode wave-guide gives fluorescence. This hap...

SOLID sequencing | Supported oligonucleotide ligation and detection
Просмотров 1,4 тыс.Месяц назад
SOLID stands for Supported Oligonucleotide Ligation and Detection. The method uses short 8 mer sequences for the detection of unknown nucleotide in the given template. out of eight, two nucleotide are very specific while the other are degenerate nucleotide. These sequences are attached with a fluorescence probe. Based on the color of fluorescence we find the unknown sequence.
Inductively coupled plasma emission spectroscopy
Просмотров 2,2 тыс.2 месяца назад
Inductively coupled plasma emission spectroscopy (ICP-ES) is an amazing technique, that uses plasma for the detection of elements in the sample. The plasma is generated by argon gas. Using RF coils alternating magnetic filed is generated. Under the influence of this magnetic field, the argon ions gets accelerated and moves under circular path. The accelerated argon ions collides with other argo...
Analytical centrifuge
Просмотров 1,9 тыс.3 месяца назад
Analytical centrifuge commonly known as analytical ultra centrifuge is a centrifuge machine that can detect movement of sample molecules during centrifugation. For this the machine uses a vertical tube rotor which is transparent from the top and the bottom. The centrifuge tube placed in the rotor is also transparent. The light is allowed to pass through the bottom of the rotor the light coming ...

The alpha helix is one of the most common secondary structure of proteins or polypeptide chain, found in the nature. In this structure the amino acids are arranged in the form of twisted coil, known as the alpha helix. The helical structure is stabilized by the presence of hydrogen bonds.

Abbe's equation and Numerical aperture
Просмотров 1,1 тыс.6 месяцев назад
Abbe was a scientist who gave the mathematical equation to calculate resolution of microscope. In this equation the denominator n sin alpha, is termed as the numerical aperture. By definition the numerical aperture is the product of refractive index and light gathering ability of objective lens.
Chromatic Aberration
Просмотров 4 тыс.6 месяцев назад
Chromatic Aberration is the phenomenon in which the edge of convex lens acts as a prism and splits white light into seven colors. This results in annoying colors in the image. To solve the problem of chromatic aberration the objective lenses are corrected. These corrected objectives can be either achromatic objective or apochromatic objective.

G protein coupled receptor | GPCR
Просмотров 19 тыс.9 месяцев назад
G protein coupled receptor (GPCR) is also called, seven trans-membrane receptor. It acts as a signalling molecule in most of the eukaryotes. It is attached with alpha beta and gamma subunits in the cytoplasm. Upon activation the alpha subunit binds GTP and activates other cellular proteins, which acts as a cell signal.
DNA foot print assay
Просмотров 6 тыс.10 месяцев назад
DNA foot print assay is a technique used to find, region of DNA where a particular protein binds. The protein can be a transcription factor, enhancer or a repressor protein. For this assay the DNA segment is amplified by PCR and then labeled. The test protein is then added to the DNA fragments to be analyzed. If the protein interacts with the DNA then DNAse I enzyme will fail to digest the regi...
Liquid Chromatography | Partition chromatography
Просмотров 36 тыс.10 месяцев назад
Liquid Chromatography or Partition chromatography, is a chromatography technique in which, the particles of solid support are coated with a liquid stationary phase. These particles are packed in the chromatography column. When sample is loaded, it gets dissolved in the liquid stationary phase around the particles. The mobile phase is usually a solvent or mixture of solvent which does not mix ea...

I have exam today 😂 in a few hour I'll be sitting for this paper 😂
Love the video, love the music
Well explained 👍🏻🤍
best explanation ever....
Good
really helpful, thanks!
great video, really hepled!
Its finalss n iam hereee once againn
Super clear presentation. Thank you!
Great explained
Thankyou somuch for this video ❤🎉
Thankyou somuch for this video ❤🎉
not bro faking accent
Hi there, great video. Do the proteins automatically enter the resolving gel (even without changing the voltage) or do they only enter into the resolving gel the moment the voltage is changed? Thanks!
Thankyou so much sir ❤
short and easy thank you
Thank you
Very very nice videos God bless you
It's truly very helpful to me. I am learning from this just before my exam. Lot's of love from India ❤🇮🇳
Nicely explain ❤
Great
I love mathematics , [ 2^(n+1) ] - 2=Number of Strand of heavy isotope , n=number of divisions 🔥🔥
Thank you so much!
This is the best video, very clear!!! Thank you so much!
Keep continuous u explain very well I see your many videos
