Storage Condition

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

Shelf Life

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Lead Time

3-7 business days

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Gene References into Functions

The authors conclude that CagQ is a membrane protein in a type IV secretion system and is crucial for maintaining CagA expression and CagA-induced apoptotic effects. PMID: 29306012
The vacuolating cytotoxin autotransporter (vacA) c1 genotype, but not cytotoxicity-associated immunodominant antigen (cagA) status, might be the first important bacterial biomarker for predicting the cardia adenocarcinoma risk. PMID: 29036792
In this study, through quantitative analysis of the complex formation between CagA and PAR1b, the authors found that several CagA species have acquired elevated PAR1b-binding activity via duplication of the CagA multimerization motifs, while others have lost their PAR1b-binding activity. PMID: 27445265
Helicobacter pylori expressing cagA and vacA genes is prevalent in dyspeptic Ghanaian patients. PMID: 28655347
H. pylori infection significantly inhibits the cleavage of TRAF1 via a CagA-dependent mechanism, which would increase the relative amounts of full-length TRAF1 and exert an antiapoptotic effect on H. pylori-infected cells. PMID: 28082808
Data indicate that treatment of gastric epithelial cells with simvastatin reduced the level of cellular cholesterol and led to attenuation of translocation and phosphorylation of cytotoxin-associated gene A (CagA). PMID: 26730715
Studies suggest that cytotoxin-associated gene A (CagA)-negative non-virulent strains of Helicobacter pylori may be a potential risk factor of pancreatic cancer. PMID: 26390415
CagT plays an important role in the translocation of CagA into host epithelial cells. PMID: 23075784
CagA upregulated CIP2A expression and this upregulation effect was dependent on Src and Ras/mitogen-activated protein kinase kinase/extracellular signal-regulated kinase pathways. PMID: 19959630
In a stomach adenocarcinoma cell line, an increase in this protein correlated with the amount of the phosphorylated protein. PMID: 16278423
These data demonstrate that VacA can downregulate CagA's effects on epithelial cells, a novel molecular mechanism showing how H. pylori can avoid excessive cellular damage. PMID: 19046339
