Dear Keith,
As far as I know, HC2 has not a CD Number (unstable
McAb)and I do not think it is commercially available.
We are using CD123 as a replacement for HC2 and preliminary
data shows that it is useful in Villous disorders. In our
hands it has shown positive in HCL and negative in other
I hope you will find this dendritic cell marker useful for
the differential diagnosis of HCL.
