GST pulldown | GST Pull Down Assay | Protein-Protein Interaction Using Pull Down Assay

this video talks about the GST pulldown assay. The glutathione S-transferase (GST) pull-down assay is a relatively easy, straightforward method to identify potential binding partners. This is an in vitro technique used to detect physical interactions between two or more proteins and an invaluable tool for confirming a predicted protein-protein interaction or identifying novel interacting partners.

[@Paola-cr4qo]

So if a protein A interacts with protein B but we need to know if it is subunit B1 or B2, can we use the same method by doing two pull down assays ( one with protein A and B1 and one with protein A and B2)? Or is there another technique for that?

[@xiBoggy]

great video

[@animatedbiologywitharpan]

xiBoggy thanks ,that keeps me motivated

[@ooiTzAmii]

Thank you! However, in future videos, maybe it would be better if you could add some possible controls for the technique. e.g. having only beads as a control to identify non-specific binding.

[@animatedbiologywitharpan]

ya i just wanted to keep it as simple as possible ....

[@shivangani9255]

Your videos are really very interesting and beneficial especially your Drosophila related. Are u working on Drosophila? as during my summer training I watched your videos for basics.

[@animatedbiologywitharpan]

shivangani lohani yup I work with drosophila neural circuitry

[@shivangani9255]

Arpan Parichha Ty for all Drosophila related videos as I will be doing my dissertation in this field only.

[@animatedbiologywitharpan]

shivangani lohani oh nice..... you can keep my whatsapp no 9051392160....if you need some help.Where you want to do desertation??

[@myriamfhal6728]

Hiii everybody ! I made a pull down essay but I dont understand how I am suppose to present the result and how I have to read it. In the video its explain really quickly in the end in 2:10 min. Someone can explain to me ? I made input WB, Pull down WB and Pull down Coomassie

[@shezotetalukder105]

this video is good and helpful but it's to fast, make it a bit slower

[@animatedbiologywitharpan]

shezote talukder these videos are made in terms of global standards..... always you can play the video in 2x speed to slow down

[@ahmadmuhammad.0163]

Make a correction in your video bro: GST is not part of plasmids, plasmids contain genes of interest, not proteins of interest. Genes of interest then encode proteins, here the GST works as bait. GST is added, not encoded by the plasmids as you have shown in your diagram.

[@animatedbiologywitharpan]

GST is a 211 amino acid protein (26 kDa) whose DNA sequence is frequently integrated into expression vectors for production of recombinant proteins. The result of expression from this vector is a GST-tagged fusion protein in which the functional GST protein (26 kDa) is fused to the N-terminus of the recombinant protein. Because GST folds rapidly into a stable and highly soluble protein upon translation, inclusion of the GST tag often promotes greater expression and solubility of recombinant proteins than expression without the tag. In addition, GST-tagged fusion proteins can be purified or detected based on the ability of GST (an enzyme) to bind its substrate, glutathione (GSH).

[@ahmadmuhammad.0163]

@@animatedbiologywitharpan agreed bro, still, you need to use word ''GST,s DNA sequence'' as you you mentioned in your reply. But in video, maybe unconsciously, you used the word GST Protein in plasmid. As you know the sequence will translate into GST protein.
