We genetically modified E. Coli with jellyfish genes for flourescence. It was probably the coolest lab we've done yet. No freakin' titrations or counting and sexing any damn fruit flies.

Sounds like you're having fun with that class.Moonbear said:Sounds like you're having fun with that class.
binzing said:FOR ONCE!
Lisa, haha. No. These E. Coli are special ones that won't survive outside of a lab environment. We actually haven't seen if they glow yet, but we can make our predictions based on what we did. Tomorrow we get to see if they glow.
lisab said:Great...let us know how it turns out.
Moonbear said:Great! As Chris points out, what you did in your biology class really is a tool used in actual research labs, not just some outdated busy-work exercise with no application beyond the classroom.
binzing said:Yeah. It was kind of scary as to how simple it was, considering that's the same method terrorists could use to create bio weapons.

It was cool but nowhere near as awesome as some of my chem labs in college.
Moonbear said:Rest assured, it's only easy because you were inserting a small gene that is known to work when transfected into the cells you were supplied with the kit used. Usually, you would transfect that GFP sequence attached to another gene of interest, and the reason for doing that is to find out if your gene of interest got into the cell and is being expressed by quickly looking for the GFP expression.
binzing said:Well mostly. Actually the to get glowing proteins the E. Coli we had had to A. have the positive gene splice for it, B. be resistant to ampicillin (sp?), and C. be in the presence or a certain chemical (ara-something).
