Figure 1: Protein structure of Fc (LALA-PG)-KIH (human) IgG1 Control (rec.) (Prod. No. AG-35B-0018).
Figure 2: Fc (LALA-PG)-KIH (human) IgG1 Control (rec.) (#AG-35B-0018) does not bind to the human Fcg Receptor I. Method: Fcg Receptor I (mouse) is coated on an ELISA plate at 1 µg/ml overnight at RT. Fc (LALA-PG)-KIH (human) IgG1 Control (rec.), a control Fc-KIH (human) IgG1 Control (rec.) (#AG-35B-0015), or a classical Fc (human) IgG1 Control (rec.) (#AG-35B-0007) are added (starting at 4000 ng/ml with a two-fold serial dilution) during one hour and then detected using an anti-human Fc (HRP) antibody. Both controls proteins bind to the mouse Fcg Receptor, while the Fc (LALA-PG)-KIH (human) IgG1 Control (rec.) shows no binding as expected with its LALA-PG mutations.

Description
Negative control in experiments with recombinant proteins fused to human IgG1 Fc (LALA-PG)-KIH (Knobs-into-Holes) (e.g. Prod. No. AG-40B-0248). This protein is not an appropriate negative control for other standard Fc protein constructs.
The protein Fc (LALA-PG)-KIH (human) IgG1 Control (rec.) is produced by using two different vectors, one encoding for the Fc (LALA-PG) Knobs sequence with a small linker (synthesizing a protein of 29kDa) and one encoding for the Fc (LALA-PG) Holes sequence (synthesizing a protein of 28kDa). Both vectors transfected into HEK293 cells produce both Fc molecules (Knobs-into-Holes technology; J.B. Ridgway, et al.; Protein Eng. 9, 617 (1996)) required for dimerization and for secretion of the final protein Fc (LALA-PG)-KIH (human) IgG1 Control (rec.). The LALA-PG mutations inhibit binding to FcγRs and C1q while FcRn binding and Fc stability remain unaffected.
