HA tag is derived from amino acid residues 98 – 106 of the human influenza hemagglutinin (HA) molecule. Recombinant proteins are often engineered to express the HA tag as a general epitope tag in expression vectors. HA tag facilitates detection, isolation, and purification of target proteins without compromising its bioactivity or distribution. HA-tagging of a recombinant protein and subsequent examination using anti-HA antibody, in either intact or permeabilized cells, allows researchers to study cellular expression levels, topology and functional activity of the HA-tagged protein. Antibody mediated detection of the HA tagged proteins further negates the need for developing specific antibodies for newly identified proteins, which are often unstable, difficult to purify, cross-reactive or poorly immunogenic proteins. Our PtX™ Rabbit Anti-HA antibody exhibits high specificity towards HA-tagged proteins and undergoes rigorous testing to ensure consistent performance and reliability.  PtX™ Rabbit Anti-HA antibody is suitable for use in Western blot and ELISA 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.
