Default Expression profiles probe id meaning?

Hello,

What is difference between different probe in the gene expression profiles?
e.g. Gene: IGF1
Probe ID: 211577_s_at, 209540_at, 209542_x_at, 209541_at

I tried to understand it from Wiki, but I would be grateful if somebody could breifly describe it for the beginners.

Thanks in advance.

They target different regions of the gene (or different transcripts). For example, you'll note that those 4 probes target transcripts with different genbank accession numbers.

Jeni, if you mean what do the different probe identification schemes mean (the _s_at, _x_at differences), have a look at http://www.affymetrix.com/support/he..._430/faq_8.jsp
