Designing a Western blot for FCGRT? The guide has the expected band size, antibodies backed by real blot images, the controls to run alongside, and protocols taken from published papers.
Open the FCGRT Western Blot GuideFacts about IgG receptor FcRn large subunit p51.
IgG in the milk is bound at the apical surface of the intestinal epithelium. The consequent FcRn-IgG complexes are transcytosed across the intestinal epithelium and IgG is discharged from FcRn into blood or tissue fluids (By similarity).
