SanjingBio's recombinant proteins are built around hot targets in development: the human HER2 ectodomain and human FRα proteins both come in His-tag versions, with FRα also available with an Fc tag, so you can choose by assay format. Every product ships with SDS-PAGE purity and ELISA binding validation data, and pairs with same-target antibodies and stable cell lines to cover antibody screening, assay development and immunogen preparation. All products can be quoted online.
