Good days, everybody ,
I have a question :
Why there is not transgenic pigs expressing human CR1 to Overcome
complement-mediated
hyperacute xenograft rejection ?
CR1 has extrinsic activity , i.e., it inactivates convertases assembled
on external
membranes, and it also exhibits intrinsic activity ,i.e., it inactivates
convertases
formed on the same membrane on which it is expressed. Among the members
of the RCA
family , CR1 is the only one that possesses dcay-accelerating activity
for both C3 and
C5 convertases in both the classical and alternative pathways,as well as
factor I
cofactor activity for the degradation of both C3b and C4b .
Would you please send me the plasmid containing the sequence for CR1 ?
