Transfection of Lyp1 and Lyp2 cDNA. T7-tagged Lyp1 (A) and Lyp2 (B) were transfected into COS-7 cells and immunoprecipitated with anti-LyP or anti-T7 antibody and blotted with anti-T7. (A) Lyp1 transfection results in a transfected protein of 105 kD and a probable degradation product of 96 kD, whereas (B) shows LyP2 as a protein of 85 kD.
