Sequence for cd44v6 - (Aug/10/2006 )

I want to design cd44v6 primer,but I search in the ncbi,I can not got cd44v6 sequence,there is cd44v1-v5,but no v6.hundreds of essays do research works on cd44v6,also many primers,i chose one,but I failed,so i search for the cd44v6 sequence,help!help!

Doesn't CD44v6 just correlate to the sequence of the sixth exon of CD44?
According to

J. Obstet. Gynaecol. Res. Vol. 32, No. 4: 379–386, August 2006

this is the case. And you should be able to get the sequence of CD44. Or not?
