Microarray 244K- what does it mean - (May/20/2012 )

Hi all,

while going through literature, I noticed some data had mentioned the format of microarray is 244K.
Can anybody please tell me what 244k means. Is it something to do with clustering.

It will be a great help if anybody could clear my doubt. (i am not sure if this is the right forum to ask such question)

Thanks,
Rose
