Clone human genes into plants! - Avidadham - International Conference on Molecular therapeutics!

E.coli VS Plants!

As an undergraduate of Biotechnology, I know about cloning. I know about cloning a gene which codes for a human protein into a bacterial cell, E.coli, most times.

I also know about producing transgenic plant varieties. But, I don't know about cloning a human gene into plant! I came to know about cloning a human gene into plant and producing the protein in plants from the workshop session of AVIDADHAM'13.

Let me explain something about this!

As you may know, eukaryotic gene has both introns and exons. So cloning a eukaryotic gene into a prokaryote will have lots of problem like splicing and post translational modification.

Generally for cloning eukaryotic gene into a prokaryote like E.coli, we do follow bottom up approach where we use mRNA to synthesise cDNA, to remove the noncoding introns. But, even if we remove the introns there will be problems with post translational modification.

So, to avoid this, we are cloning our gene from human into plants? Here, we are not going to grow the plant cells, but, the whole plant.

Plant tissue culture

I had come to know that they had successfully expressed the protein of interest in plants but the problem is with purifying and extracting the protein from the plants. Once this is possible, once the extraction procedures are found, once the extraction is done with out affecting the protein's activity, then, I'm sure, this is going to be a ground breaking technique.

We could get bulk amount of our protein. But there are lots of problems when we come to the ethical side, these GM plants should be grown only inside a green house, so that it won't affect the other wild varieties by pollination.

If we are growing this in open field then due to pollination there is a possibility that our wild varieties might become extinct. So, we must grow these plants inside the green house.

After all, if we come out with an idea saying "GM plants", there are people who are ready to boycott!

But, I got very much excited about this idea of cloning human genes into plants. It's awesome, isn't it?

Any queries? Feel free to comment! I'll try to answer my best!

Lowry Assay Principle and procedure

Though there are several protein assays available, the most preferred one in many laboratories is "Lowry assay". It is effective in the concentration range of 0.01 mg/ml to 1 mg/ml. And, as an additional info, the paper published describing the procedure and principle of Lowry Assay is the most cited paper in the scientific history. (Feeling like, "Wow! I want to publish one to compete with Oliver.H. Lowry"??? :P) Why Lowry? Though there are several other protein assays, mostly Lowry assay is used in many laboratories. The reasons for preferring Lowry are: sensitivity of the assay, highly reproducible, cost effective, easy to perform. Biuret assay is generally used for higher protein concentrations like tissue samples but, Lowry for less concentrated samples and hence used in most of the molecular biology laboratories where there will be need for assaying comparatively less concentrated protein samples (in most cases where we attempt to produce enzymes).

Sea Butterfly!

Neih hou! Don't roll you eyes wondering what it is! "Neih hou" is how you say "hello" in Cantonese. Guess what, I am in Hong Kong and therefore the language Cantonese. I came to Hong Kong this summer as an intern before officially joining as a PhD Student. This is my second experience abroad, far away from home, new language, new culture, I expected me to have a "really" bad cultural shock, but, actually I experienced only 50% of what I expected. For a girl who have used the marina beach only for eating "sundal", bikini in beach was a shock (FEEL FREE TO JUDGE ME!). The first time, I went to the big wave beach here, I was the only one who was totally covered, when everyone was enjoying their Beer, I was slowly sipping my lemon juice (THE ODD ONE OUT!). I realized how beautifully different the world outside is! There is no single standard for right or wrong, it varies in different countries, in different regions around the world. And it ...

The Butterfly flew for the first time!

Hi dear sweet lovely reader, Didn't meet you for a long time... Just after complaining about the stipend problem in the last post, I actually wanted to write a lot here, but, couldn't find time (Such a lazy girl, I am!). As you might be knowing, the author (me) is the butterfly here :P And, I flew for the first time!! YEAH! I FLEW! I flew like a butterfly! It was an awesome experience flying for the very first time! (ow, no! I dint put a trans-gene in my body and fly after getting a pair of wings, but with a passport and VISA). I'm this girl, full of dreams wishing to do "this", "that" and "all kind of stuffs that one can do". And, one among those dreams was to fly one day! TO FLY FREE!(I mean, not free of cost :P, but liberation) I always wanted to fly in those big, big airplanes, but, I always have avoided that mode of transport. Reason? Obviously, it would burn a big hole in my dad's pocket (actually he can afford if I wan...
