| Product Name | Recombinant Human ErbB2 Her2 His Tag Extracellular Domain Protein >=95% Purity 1 mg |
| Catalog No. | AATM-HMM-0042 |
| Description | This recombinant human ErbB2 (Her2) protein carries a His tag and comprises the extracellular domain encoded by the human ErbB2 sequence (NM_004448.3). It is expressed in HEK293 mammalian cells and purified to high homogeneity. The protein exhibits an apparent molecular weight of 95-115 kDa as determined by SDS-PAGE analysis, with a purity of at least 95%. It is formulated in PBS at pH 7.4 and supplied in 1 mg aliquots. ErbB2 is a receptor tyrosine kinase overexpressed in breast cancer and serves as a critical biomarker for cancer screening and therapeutic targeting. The product is shipped with cold packs to maintain stability during transit. |
| Intended Use | For research use only in breast cancer screening studies, therapeutic antibody development, and diagnostic assay research. Not for use in human experiments. |
| Principle / Technology | Recombinant expression of the human ErbB2 extracellular domain in HEK293 cells with His tag for affinity purification and immunological characterization. |
