Claim 2
Dependent Claim
46 words
A human LHR (HuLHR) comprising the carbohydrate binding domain, the epidermal growth factor domain and a complement binding domain of the amino acid sequence shown in FIG. 1 purified to show a single band on SDS-PAGE as visualized by silver stain, and having LHR biological activity.
Claim 3
Dependent Claim
