I think that Sigma Chemical, USA sells this, they have a huge selection
of lectins. Alternatively, you can prepare your own from common lentils
by extraction into normal saline or PBS followed by centrifugation to
remove debris and lipids. Ammonium Sulfate precipitation will pull down
the proteins. Dialyze into PBS and centrifuge out debris, then load
onto a column of the appropriate sugar immobilized ontoagarose. I can't
recall the specificity at the moment. Elute with more of the same sugar
and then dialyze it off. I did this kind of thing about ten years ago,
the details are sketchy. If you are interested, I can look into it.
