Specifications
Description CD19 is a well-known biomarker expressed on most normal and malignant B cells and used as a target antigen found in B cell malignancies. CD19, also known as B lymphocyte antigen CD19, B lymphocyte surface antigen B4, T cell surface antigen Leu-12, and CVID3, is a transmembrane protein encoded by the gene CD19 in humans. This 95 kd transmembrane glycoprotein belongs to the immunoglobulin superfamily with two extracellular C2 group Ig-like domains and a relatively large cytoplasmic tail that is highly conserved across mammalian species. CD19 is expressed on all normal, mitogen-stimulated, and malignant B cells, with the exception of plasma cells. CD19 is ubiquitously expressed at all stages of B cell development and its surface expression is highly regulated. Because it is ubiquitously present on all B cells, it can serve as a B cell marker and a target for immunotherapy against neoplastic lymphocytes. This product is designed as a tool for the delivery and expression of mouse anti-CD19-TF CAR mRNA for research. The product leverages the lipid nanoparticle (LNP) technology platform for simple and efficient delivery of mouse anti-CD19-TF CAR mRNA to a variety of mammalian cells in vitro and in vivo. The LNPs used are formulated with SM-102, DSPC, cholesterol and DMG-PEG2000 at an optimal molar concentration for a high rate of encapsulation and efficient mRNA delivery. The mouse anti-CD19-TF CAR fusion protein in this product is approximately 58 kD and consists of mouse anti-CD19 scFv (single-chain variable fragment) linked to a second-generation CAR (chimeric antigen receptor) containing the CD8 hinge and transmembrane domain and 4-1BB and CD3ζ signaling domains. It contains an additional C-terminal TF tag (15 amino acids)

Technical Notes Work with mRNA-LNP on ice. It is important to minimize the time that the product spends at room temperature; after handling product during experiments, return immediately to ice.Upon receiving product, briefly pulse spin before opening to ensure product is at bottom of container; it is important not to spin for too long as this may rupture mRNA-LNP’s. Do not vortex. mRNA-LNP products should only be handled with certified RNAase-free reagents and consumables; use of filtered pipette tips is highly recommended
