Hi everyone,

Could someone please give me information on:

1. Whether they know if polyclonals are available against 
the CD 57 antigen on natural killer lymphocytes.  

2. What other positive controls they have successfully 
used, apart from human lymph node and tonsil, for the HNK-1 
antibody. 
Thanks.
