VivoCAR™ Anti-CD22 (h10F4v2) h(CD28-41BB-CD3z) CAR circRNA features a sophisticated humanized ScFv (h10F4v2) designed for optimal compatibility with the human immune system during in vivo applications. The importance of the h10F4v2 clone lies in its reduced immunogenic profile, which is critical for preventing the premature clearance of CAR-expressing cells in multi-dose circRNA regimens. This product leverages the circular RNA architecture to provide a durable yet transient expression profile, allowing for the safe and effective targeting of CD22+ cells in both oncology and systemic autoimmune research settings.

CD22

Common Name
CD22

Alternative Names
SIGLEC2, SIGLEC-2, B-lymphocyte cell adhesion molecule, B-cell receptor CD22

Full Name
B-cell receptor CD22

Introduction
CD22 is a Siglec family member (Sialic acid-binding Ig-like lectin) found on the surface of mature B cells and most B-cell malignancies. It functions as an adhesion molecule and a negative regulator of B-cell receptor signaling. CD22 is often targeted in cases of CD19 relapse due to antigen escape.

Targeting Diseases
B-cell Acute Lymphoblastic Leukemia (B-ALL), Non-Hodgkin Lymphoma (NHL)

UniProt ID

Generation
Third

Description of Signaling Cassetes
The third-generation signaling cassette integrates two costimulatory domains, CD28 for initial robust expansion and 4-1BB for enhanced persistence, coupled with the primary CD3zeta domain for potent cytotoxic T-cell function.

Storage
Aliquot and store at -80°C. Avoid freeze/thaw cycles.

Handling
Thaw and work with RNA on ice. Upon first use, pulse spin before opening and aliquot into single use portions. DO NOT vortex. Use only certified RNase-free reagents and consumables with proper RNase-free technique. Use of barrier tips is recommended. Avoid freeze/thaw cycles. DO NOT mix with media containing serum unless first complexed with a stabilizing transfection reagent.
