LDL receptor

[PT112 at PHOENIX.CAMBRIDGE.AC.UK]

Dear Netters:
    I believe I isolated a C. elegans low-density lipoprotein (LDL) 
receptor gene. Is there anybody knows how to isolate LDL from the
worm and label it. Also, do you have any idea why a free-living
nematode feeds on bacteria needs a LDL receptor.
   Thank you in advance for your help.
