FITC-Labeled Human IgG1 Fc Protein, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90% (With Star Ribbon Pre-stained Protein Marker).
The purity of FITC-Labeled Human IgG1 Fc Protein, His Tag (Cat. No. IG1-HF2H3) is more than 85% and the molecular weight of this protein is around 65-80 kDa verified by SEC-MALS.
2e5 of HEK293/Human FcRn (FCGRT & B2M) Stable Cell Line (Cat. No. CHEK-ATP079) were stained with 100 μL of 10 μg/mL of FITC-Labeled Human IgG1 Fc (C103S, M135Y, S137T, T139E, H316K, N317F) Protein, His Tag (Cat. No. IG1-HF2H3) and negative control protein respectively. FITC signal was used to evaluate the binding activity (QC tested).
