Human Anti-CD44 (clone RG7356) scFv-Fc Chimera (CAT#: VS-0125-FY25)
The anti-CD44 single-chain antibody-Fc (scFv-Fc) construct is a molecular design that combines a single-chain antibody (scFv) with the Fc region (typically derived from human immunoglobulin G, IgG). This design aims to enhance the stability of the antibody, prolong its circulation half-life, and increase its affinity for the target. CD44 is a glycoprotein widely expressed on the surface of various cell types and is involved in multiple biological processes such as cell adhesion, migration, and proliferation. Given that CD44 is expressed in a variety of tumor cells, the anti-CD44 scFv-Fc construct has the potential to serve as a multifunctional PET imaging agent for the diagnosis and monitoring of different types of CD44-positive tumors. Future clinical studies will help validate its efficacy and safety in tumor imaging, promoting its application in precision medicine for cancer.
We specialize in custom recombinant antibody production, offering seamless execution from provided sequences to high-quality antibody deliverables, ensuring optimal yield and purity.

Applications
- Application Notes
- The potential function of anti-CD44 scFv-Fc lies in its ability to selectively target and visualize CD44-positive tumor cells. Given that CD44 is a glycoprotein frequently overexpressed in various cancers and cancer stem cells, this targeting could facilitate the imaging of these malignancies. Additionally, the interaction of CD44 with hyaluronic acid (HA) has implications for the activation of several cell signaling pathways that may contribute to enhanced cell proliferation, survival, and invasion. Thus, targeting CD44 presents a promising strategy for cancer therapy.

- Post Translation Modifications
- Proteolytically cleaved in the extracellular matrix by specific proteinases in several cell lines and tumors.
N-glycosylated.
O-glycosylated. O-glycosylation contains more-or-less-sulfated chondroitin sulfate glycans, whose number may affect the accessibility of specific proteinases to their cleavage site(s). It is uncertain if O-glycosylation occurs on Thr-637 or Thr-638.
Phosphorylated; activation of PKC results in the dephosphorylation of Ser-706 (constitutive phosphorylation site), and the phosphorylation of Ser-672.
- Protein Refseq
- NP_000601.3; NP_001001389.1; NP_001001390.1
- Function
- Cell-surface receptor that plays a role in cell-cell interactions, cell adhesion and migration, helping them to sense and respond to changes in the tissue microenvironment.
Participates thereby in a wide variety of cellular functions including the activation, recirculation and homing of T-lymphocytes, hematopoiesis, inflammation and response to bacterial infection.
Engages, through its ectodomain, extracellular matrix components such as hyaluronan/HA, collagen, growth factors, cytokines or proteases and serves as a platform for signal transduction by assembling, via its cytoplasmic domain, protein complexes containing receptor kinases and membrane proteases.
Such effectors include PKN2, the RhoGTPases RAC1 and RHOA, Rho-kinases and phospholipase C that coordinate signaling pathways promoting calcium mobilization and actin-mediated cytoskeleton reorganization essential for cell migration and adhesion.
