Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Description

The Recombinant Human MAGEA4 is a full-length melanoma-associated antigen 4 protein, which spans the 1-317aa expression region. Produced in mammalian cells, this protein is essential for cancer research. With a C-terminal 10xHis-tag, MAGEA4 displays a purity greater than 90% as confirmed by SDS-PAGE analysis. The endotoxin levels are kept under 1.0 EU/µg, as determined through the LAL method. The functionality of MAGEA4 is demonstrated in a binding assay, where immobilized MAGEA4 at 2 μg/mL can bind anti-MAGEA4 recombinant antibody with an EC₅₀ range of 30.33-43.10 ng/mL. The product comes in a lyophilized powder form for convenient storage and application in various research projects.

Target Background

Function

Regulates cell proliferation through the inhibition of cell cycle arrest at the G1 phase. Also negatively regulates p53-mediated apoptosis.

MAGEA4 was positively correlated with TWIST1, and its knockdown inhibited EMT in TE3 cells. PMID: 28653599
Because of the significant correlation of MAGEA4 and indices of poor prognosis, the role of this CTA may be confirmed in Esophageal squamous cell carcinoma (ESCC) aggressiveness and metastasis. Therefore, MAGEA4 may be a promising therapeutic candidate for suppressing ESCC aggressiveness PMID: 30197348
Study shows that whereas MAGEA4 expression by itself may be indicative of a poor prognosis in primary lung cancer, its prognostic value depends entirely on its subcellular localization and on the p53 status. The accumulation of nuclear MAGEA4 expression without p53 expression is significantly associated with poor survival, implying that MAGEA4 inhibits apoptosis and increases tumorigenesis.
