CD19 Antibody

Rabbit antibody targeting CD19 (B-lymphocyte antigen CD19), a cell-surface protein involved in B-cell development and immune signaling.

Catalog No.: 0544-MBS8527293-01 Size: 0.1 mL

Product Overview

CD19 Antibody is designed to recognize CD19, also known as B-lymphocyte antigen CD19 or B4. CD19 is a transmembrane glycoprotein expressed primarily on B-lineage cells and plays an important role in regulating B-cell receptor signaling and immune responses.

This antibody is produced by immunizing rabbits with a synthetic peptide corresponding to a region of CD19 conjugated to keyhole limpet hemocyanin (KLH). According to the supplied product information, the antibody shows reactivity with human and mouse CD19.

CD19 is widely studied in immunology, B-cell biology, hematological research, and investigations of immune-related diseases. Confirm the suitability of the antibody for your intended application using the manufacturer's product documentation.

Biological Background: CD19

CD19 is a cell-surface glycoprotein that acts as an important regulator of B-cell receptor signaling. It participates in a signaling complex that helps modulate B-cell activation and responses to extracellular antigens.

Because of its expression across many stages of B-cell development, CD19 is an important research marker in studies of B-cell populations, immune function, and B-cell-associated malignancies. Its biological role also makes it relevant to research into targeted immunotherapies.

Research Applications

  • Investigation of CD19 expression in human and mouse research samples.
  • Studies of B-cell development, differentiation, and activation.
  • Research into B-cell receptor signaling and immune regulation.
  • Studies of B-cell-associated hematological malignancies.
  • Exploration of CD19 as a biological marker in immunology research.
Application Note

The supplied information does not specify a validated assay application or working dilution. Consult the manufacturer's datasheet to confirm suitability for Western blot, immunohistochemistry, immunofluorescence, flow cytometry, or other intended techniques before use.
