Background Information

FBF1, also named as ALB and KIAA1863, is keratin-binding protein required for epithelial cell polarization. It is involved in apical junction complex (AJC) assembly via its interaction with PARD3. FBF1 is required for ciliogenesis. FBF1 has six isoforms with MW 125-127 kDa, 99 kDa, 69 kDa and 55 kDa. This antibody is induced by N-terminal (20-347aa) of FBF1. It recognizes all the six isoforms.

Karine (Verified Customer) (02-26-2024)

FBF1-Coralite488 (in green) does label one extremity of the primary cilium labeled with ARL13B (in red) in RPE1 cells whose nuclei appear in purple and cell contour in grey with Brightfield. It is quite specific when used at 1/1000 overnight at 4°C. There is a bit more aspecific signal than with the uncoupled antibdy but it remains quite reasonable.
