Well, yes. In this particular experiment, the expression of a particular protein affected the detachment properties of the cell expressing it. It did not affect the adhesion however. I really am looking for the difference between the two, nothing with the factors that cause it. I just don't get...

No one can help me out here?

Hello all, I am reading some primary literature in which they talk about cell adhesion and cell detachment. They describe different assays for each. My question is, how are these two different? It seems that high detachment is the same as low adhesion, but according to the article, for a...

Thanks everyone for help understanding this! Monique, your explanation of antibodies and effinity was particularly clear. Thanks Again!

Thank you for the responses. Both were extremely helpful. I guess all I am wondering now is how do we predict the affinity of an antibody for a given antigen? I am assuming that this is purely a chemistry question, but I'd really like to know. Again thanks, it is nice to get help in something...

Hi, I have a question concerning fluorescence microscopy and the use of antibodies to stain cells. I am a little confused about the acutal procedure. That is, I don't know where the antigen and the antibodies come from. Are they introduced by the experimenter, or are they naturally occurring...

I was wondering what viscoplasticity is. I am familiar with viscoelasticity, but I heard the term viscoplasticity mentioned in an internet article the other day and I did not know what was meant by it. Could anyone give me a general definition or a good link? I searched myself with a simple...

Hey everyone, thanks!

In looking at various stainless steels, I notice that S and P are added to "improve machinability." What is the mechanism here? And what exactly makes a material "machinable"?

Ok, then static fatigue in ceramics is actually referring to failure by cracking due to residual/constant stresses. Then plastic deformation is not a consideration here. Do glasses and ceramics exhibit creep at all?

What is the difference between these two phenomena? Or are they the same thing? I have heard both terms used in different classes, but they seem to be the same or similar.

Hey everyone, I was wonderinig if someone could recommend a good text on electrical properties of materials. I'm looking for something very comprehensive that can be referenced easily, but is relatively in depth. Any suggestions?

I'm a student working on some theoretical transition metal nitride hard coatings. I'm involved in sputter deposition and also electron microscopy of samples. However, I do not know a lot about industrial uses of hard coatings. I was wondering if someone could give me insight into some...

I'm trying to understand the mechanisms behind precipate hardening, and I am not able to find a good source to explain the differences in coherent precipitates and dispersion hardening. I understand that the crystal structure of the precipitate is different in dispersion hardening (that's what I...

Of course! I will just laugh at myself in this situation and look back on it when I am 3/4 through this semester of advance thermo. It's just funny that I chose to mess up the easy stuff. I think it is a habit with me!
