Recombinant Proteins

View Collection

Recombinant proteins are proteins expressed and purified in engineered host cells using recombinant DNA or recombinant RNA technology. This technology enables highly efficient and precise expression of target proteins with excellent batch-to-batch consistency and scalability. Currently, recombinant proteins have been widely applied in multiple important fields including protein structure and function research, drug discovery and development, in vitro diagnostic reagent design, cell functional assays, and immunoassays.

Product Advantages

Wide variety of product types
Over 90% expressed in HEK293
High batch-to-batch consistency
Low endotoxin

For key steps in cell proliferation, differentiation, and survival, stable and efficient growth factors are the cornerstone of experimental success.

HUABIO employs an advanced HEK293 mammalian cell expression system to provide recombinant growth factors with native conformation and activity, and high batch-to-batch consistency. Our strict endotoxin removal and purification processes ensure every product delivers superior quality with extremely low endotoxin levels.

Choose HUABIO to eliminate variables from your cell culture and achieve stable, reproducible results.
