• Specifications

  • Species of Origin

    Mouse

    Expression system

    CHO

  • Affinity Tag

    His Tag (C-term)

    Buffer

    Lyophilized from a 0.2 µm filtered solution of PBS, pH 7.4

  • Purity

    >95% as determined by SDS-PAGE analysis.

    Molecular weight

    The protein has a calculated MW of 30.38 kDa.
    The protein migrates as 30-42 kDa under reducing condition (SDS-PAGE analysis).

  • Activity

    Measured by its ability to bind anti-mouse CD19 antibody in functional ELISA. Immobilized anti-mouse CD19 antibody at 2 μg/mL (50 μL/well) can bind Recombinant Mouse CD19 Protein.

    Endotoxin level

    <0.1 EU per 1 μg of the protein by the LAL method.

  • Form

    Lyophilized

• Background

  • Background

    CD19 protein, present on the surface of B cells, acts as a key regulator of B cell development and function. It plays a crucial role in B cell receptor (BCR) signaling, promoting B cell activation, proliferation, and differentiation upon antigen recognition. CD19 also enhances B cell responsiveness to co-stimulatory signals from T cells. Due to its selective expression on B cells and absence on other immune cells, CD19 serves as a valuable target for immunotherapy in B cell malignancies such as B cell lymphomas and leukemias. Understanding CD19 biology is essential for developing targeted therapies for B cell-associated disorders.

    Synonyms

    Differentiation antigen CD19, B-lymphocyte antigen CD19

  • Uniprot ID

    P25918

    Sequence Note

    Met1-Gly287

• Instruction

  • Reconstitution

    It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration of 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

    Shipping

    The product is shipped with polar packs. Upon receipt, store it immediately at -20°C or lower for long term storage.

  • Stability & Storage

    This product is stable after storage at:

    • -20°C for 12 months in lyophilized state from date of receipt.
    • -20°C or -80°C for 1 month under sterile conditions after reconstitution.

    Avoid repeated freeze/thaw cycles.
