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 ?
