Vimentin expression in human malignant glioma cells depends on cellular density， algorithms of drug delivery and chemo/radio treatment. Vimentin and detyrosinated microtubules provide structural support for the extensive microtentacles observed in detached tumor cells and a mechanism to promote successful metastatic spread. Primary colorectal carcinomas display aberrant expression of vimentin， and have activated Notch and TGFbeta signaling pathways. Vimentin is a strong arterial substrate for transglutaminases. Transglutaminase-mediated vimentin dimerization results in a novel unifying pathway by which vasodilatory and remodeling responses may be regulated. Ablation of vimentin expression inhibits migration and invasion of colon and breast cancer cell lines. Vimentin is the main intermediate filament protein in mesenchymal cells and is therefore of value in the differential diagnosis of undifferentiated neoplasms.

溶解建议
Sterile Filtered White lyophilized （freeze-dried） powder. The protein （1mg/ml） was lyophilized with 30mM Tris/HCL， pH 8， 9.5M urea， 2mM EDTA， 2mM DTT 10mM methylammonium chloride. It is recommended to reconstitute the Vimentin in sterile 18MΩ-cm H2O not less than 100ug/ml， which can then be further diluted to other aqueous solutions.
保存建议
for 3 weeks， should be stored desiccated below -18℃. Upon reconstitution Vimentin should be stored at 4℃ between 2-7 days and for future use below -18℃.
For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）.
Please prevent freeze-thaw cycles.
