STRs, SSRs and microsatellites - Where is the difference?

Postby Zolt7 » Thu Dec 02, 2010 10:43 am

Hi!
In literature I've read that SSRs (Simple Sequence Repeats) mean a repetition of 1-6 basepairs.
For example: AGGAGGAGGAGGAGGAGGAGG

But I have also read the same definition for the Short Tandem Repeats (STRs).

Now I am wondering if there is any difference?

And when do I call it a "microsatellite"? Is a SSR/STR only called "microsatellite" if it has
reached a certain amount of these repetitions?

I hope you can help me.

best regards,
Zolt7

Simple sequence repeats, short tandem repeats and microsatellites are all the same thing the only difference is the name.

They are all repetitive sequences of 1-6 base pairs.
It is up to you what you call them but I prefer to use short tandem repeat.
Hope this helps,

Yeh it is a little confusing that they have more than one name, I was the same when I did my undergraduate degree and came across it :)
