This construct is meant for detecting cancer cells that express CEA, carcioembrional antigen by bacterial cells. It is expressed by the bacterial cells on their surface and can be used to detect the tumor by as it causes the bacteria to bind to cancer cells. This device contains two different parts whose production is controlled by a constitutive strong promoter J23101* (BBa_K4375003). The anti-CEA Nanobody (BBa_K4375006) is at the N-terminal, tagged with a c-myc for detection. The Nanobody is fused to the Intimin part, which is a 12-stranded β-barrel protein found in bacterial adhesins (BBa_K4375012). Specific interaction can be detected by two tags: Myc (BBa_K4375014) and anti-E, or via the fluorescence of the sfGFP at the C-terminal.

anti-CEA Nanobody Display System


This construction consists of 4 described parts. These are: J23101* (BBa_K4375003), anti-CEA-specific Nanobody, (BBa_K4375006 ), Intimin (BBa_K4375012), Myc (BBa_K4375014). They allow the bacterium to bind to the cancer cell surface, thus allowing its visualization and colonization on the tumor surface.

This construct is meant for detecting cancer cells that express CEA, carcioembrional antigen by bacterial cells. It is expressed by the bacterial cells on their surface and can be used to detect the tumor by as it causes the bacteria to bind to cancer cells. This device contains two different parts whose production is controlled by a constitutive strong promoter J23101* (BBa_K4375003). The anti-CEA Nanobody (BBa_K4375006) is at the N-terminal, tagged with a c-myc for detection. The Nanobody is fused to the Intimin part, which is a 12-stranded β-barrel protein found in bacterial adhesins (BBa_K4375012). Specific interaction can be detected by two tags: Myc (BBa_K4375014) and anti-E, or via the fluorescence of the sfGFP at the C-terminal.
