Serum albumin is a major protein component of plasma with a molecular weight of 66kDa. It is synthesized in the liver as a non-glycosylated, negatively charged protein, capable of binding numerous lipophilic compounds, transporting fatty acids and regulating blood osmotic pressure. Our PtX™ Rabbit Anti-BSA binds bovine serum albumin and is suitable for use in Western blot and ELISA applications.

Figure 1. ELISA Dose Response curve showing increasing absorbance at 370 nm with increasing amounts of PtX™ Rabbit Anti-BSA detecting 0.1 ng/µl BSA Standard Antigen.

Figure 2. Western blot analysis of PtX™ Rabbit Anti-BSA. Lanes 2 – 6: Decreasing amounts of Bovine Serum Albumin Protein were run on the SDS-PAGE. Separated bands were transferred to the membrane and PtX™ Rabbit Anti-BSA (1: 5 000) was used to detect the antigen. The bands (~66 kDa) were visualized in each lane following the addition of anti-rabbit secondary antibody with HRP and substrate. Our antibody was able to detect antigen amounts upwards of 5 ng (Lane 6).

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.
