|Calculated MW||19979 Da|
|Other Names||Anterior gradient protein 2 homolog, AG-2, hAG-2, HPC8, Secreted cement gland protein XAG-2 homolog, AGR2, AG2|
|Target/Specificity||A synthetic peptide corresponding to residues in human AGR2 was used as an immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|

The anterior gradient protein-2 (AGR2) is a cancer cell marker specifically up-regulated in response to depletion of serum and oxygen. It has been identified as a tumor marker in primary and secondary cancer lesions, and as a marker for detection of circulating tumor cells. Elevated levels of AGR2 are known to increase the metastatic potential of cancer cells (1). Specifically, AGR2 may serve as a useful molecular marker and/or potential therapeutic target for hormone-responsive breast tumours (2). AGR2 expression promotes tumor growth in esophageal adenocarcinoma cells as well. Expression was detected in proliferating and differentiated intestinal cells of secretory lineage, suggesting that AGR2 may be important for the growth and development of the intestine as well as esophageal adenocarcinomas (3).
