DNA ambiguity code?

 Below is the reply I got from our resident DNA expert:

Hi Bill

My international codes does not include L either so I am also stumped as to what it refers to.  I suggest using a blast seach of the sequence and see what bases are in that position with returned sequences.

Taxacomers,

I've been tracking down some PCR primers to use in study. One primer I came across and want to use includes the letter "L" as a base in the sequence...

5' - CCTCCGTAGCCCACAYLTGYCG - 3'

I'm assuming the "L" is meant as an ambiguity code but the IUPAC code does not include the letter "L." Any ideas what this letter represents?

Thanks,
