Surface sterilization of explant and Callus culture | QUICK DEMONSTRATION VIDEO

This video demonstrates the basic steps involved in sterilizing an explant and culturing the explant for callus growth. Make sure you follow your protocol while doing the experiment and add the required nutrients in media according to the defined composition along with the phytohormones required for callus growth.
This video is just for online teaching purposes and hence, time required for explant washing and callus growth is not indicative.

thank you...it is beneficial

Thank u for this informative video

no gloves for using HgCl2?

Can you suggest this method of surface cleaning for wild mushroom specimen

Thanku mem aagya samaj me steralization

[@biomedgp]

Glad to know this.

[@bijanmozafari3826]

all of these materials are prior autoclaved?

[@jadavsagar1983]

Are u using forceps of how many mm

[@danieljheelan5256]

Namaste, Bonne année. On what explant are you working on? Also, do you put a product on the cotton plug. I am unable to do TC. Thanks for your support. Shiam Daniel Jheelan from France

What problem did you face while performed TC?

[@KARAN_611]

Which media is used ?

[@sambitbanerjee7843]

As I want to learn tissue culture

[@lxldigvijaylxl]

Tissue paper is clean?is there any chance of contamination during this soaking water process

[@mahyarshokraeian]

I think her cultures will have a tremendously high chance of contamination! She's making a lot of mistakes! 1. Not wearing gloves 2. Not flame sterilizing her forcep and scalpel 3. Using unsterile paper towels 4. Using HgCl before ethanol instead of doing ethanol first and then HgCl 5. Not measuring the time that explants stay in HgCl and Ethanol

@@mahyarshokraeian Agree with most of what you said, but gloves are not used for in vitro culture, it is very dangerous to work with gloves close to flame, take care !

[@sambitbanerjee7843]

After placing the media in patri plate what to do and how can I place the media in culture tube please guide me madam.

[@biomedgp]

Yes, you can place the media in culture tubes. You can make slants to culture your explant. For placing the media in the culture tubes, you can simply pour the sterilized media and keep the tubes in slant position over a surface and leave for solidification.

[@kalpanarautela320]

Hello madam, after callus induction, the callus is not growing in size and mass ...which ultimately gets degenerated, what should I do.. ? Thank you in advance for your kind help 🙏

[@biomedgp]

You can try combinations and permutations of high cytokinins: auxin. Try to subculture it. It could be due to the depletion of media.

How to prepare 0.1% mercuric chloride mam

[@thomfraleigh2499]

You don't. There are a number of much safer alternatives that can be used for plant explant sterilization.

[@babusona3217]

Use 14 mg hgcl power with 86 ml distilled water 💦

[@abhishekrajurs7315]

2:38 Shouldn't we have to use distilled water dip after every step of washing 🙄 4:13 omg you need to wipe towards you in one direction otherwise the microorganisms will spread and remain there only
