BASIC PARTS

Part Number Part Name Description
BBa_25GIFA8M SlpA signal peptide (Lactobacillus) Encodes the SlpA signal peptide (MKKNRLIVSAAAAALLAVAPVAAS) used to route heterologous proteins to the Sec secretion pathway in Gram-positive bacteria such as Lactobacillus.
BBa_255A3G83 Igκ signal peptide (mammalian) Encodes the Igκ signal peptide (METDTLLLWVLLLWVPGSTG) for N-terminal fusion to proteins, directing them into the endoplasmic reticulum and secretion into the extracellular medium in mammalian systems.
BBa_25M9LXNV anti-IL-23 scFv (ustekinumab-derived) Encodes an anti-IL-23 scFv based on the variable regions of ustekinumab, an FDA-approved monoclonal antibody targeting the IL-12/23 p40 subunit. Arranged as VH–(G4S)₃–VL for minimal monomeric expression and antigen binding.
BBa_25K895MQ anti-IL-23 scFv (risankizumab-derived) Encodes an anti-IL-23 scFv based on the variable domains of risankizumab, a clinically validated antibody targeting the p19 subunit of IL-23. Arranged as VH–(G4S)₃–VL to preserve paratope geometry in a monomeric format.
BBa_25D0JS44 anti-IL-23 scFv 1 Encodes a de novo designed scFv against IL-23 in VH–(G4S)₃–VL format. When fused to a secretion signal, the scFv is secreted into the supernatant and detected by anti-His Western blot, showing dose-dependent IL-23 binding in ELISA.
BBa_25A5L3IO anti-IL-23 scFv 2 Encodes a de novo IL-23-binding scFv in VH–(G4S)₃–VL format. Designed for secretion and detection by anti-His Western; validated by ELISA showing dose-dependent IL-23 binding.
BBa_25C0CV3I anti-IL-23 scFv 3 Encodes a third de novo IL-23-binding scFv (VH–(G4S)₃–VL). When fused to a secretion signal, the scFv is secreted into the supernatant and shows specific, dose-dependent IL-23 binding in ELISA.

COMPOSITE PARTS

Part Number Part Name Description
BBa_256J0TP3 SlpA – anti-IL-23 scFv (ustekinumab-derived) – 6×His (Lactobacillus) Composite of SlpA signal peptide (N-term) + ustekinumab-derived scFv (VH–(G4S)₃–VL) + 6×His (C-term). Designed for secretion in Lactobacillus, enabling downstream detection/purification via His tag.
BBa_25003G8U Igκ – anti-IL-23 scFv (ustekinumab-derived) – 6×His (HEK293T) Secreted ustekinumab-derived scFv expressed in HEK293T via the Igκ signal peptide; detectable in supernatant by anti-His Western blot and validated for recombinant IL-23 binding by ELISA.
BBa_25M7O5CL Igκ – anti-IL-23 scFv (risankizumab-derived) – 6×His (HEK293T) Produces a p19-specific scFv secreted from HEK293T using the Igκ signal peptide; enables detection or purification through the C-terminal 6×His tag.
BBa_255SGXRQ Igκ – anti-IL-23 scFv 1 – 6×His Uses the Igκ leader to secrete a de novo scFv from mammalian cells (e.g., HEK293T/HEK293/CHO). The 6×His tag enables anti-His Western detection or Ni-NTA/Co-IMAC purification.
BBa_2588S786 Igκ – anti-IL-23 scFv 2 – 6×His Employs the Igκ signal peptide for secretion of de novo scFv 2 from mammalian cells. The C-terminal His tag allows anti-His Western detection and nickel/cobalt affinity purification.
BBa_25DC5U67 Igκ – anti-IL-23 scFv 3 – 6×His Expresses de novo scFv 3 secreted by mammalian cells through the Igκ leader. His-tagged for convenient detection/purification via anti-His Western or Ni-NTA/Co-IMAC chromatography.
