CD20 is a cell surface protein expressed predominantly on B cells, playing a crucial role in their development, activation, and differentiation. It is involved in regulating B cell signaling and is implicated in B cell-mediated immune responses. CD20 is an appealing target for research due to its selective expression on B cells, making it a potential therapeutic target for B cell malignancies and autoimmune disorders. PtX™ Human Anti-CD20 (1F5) enables researchers to investigate the distribution, activation, and maturation of B cells in different physiological and pathological contexts. This antibody is rigorously validated to ensure high specificity, sensitivity, and reproducibility, and is suitable for ELISA blot applications.

PtX™ | Plant-Based Expression

The biotechnology behind the development and manufacture of this product, transient plant-based expression, effectively turns Nicotiana benthamiana plants into single-use, biodegradable bioreactors. Infiltrating this plant species with Agrobacterium tumefaciens cells, transformed with our proprietary plant expression vectors, allows rapid production of a wide variety of recombinant proteins. Plants are harvested and proteins extracted by various stages of filtration, clarification, purification, and polishing – resulting in a highly functional final product.
