General tips：For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging：1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition：Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Biological Activity of Oseltamivir phosphate

Description

Oseltamivir phosphate is a neuraminidase inhibitor recommended for the treatment and prophylaxis of influenza A and B.In Vitro:Oseltamivir phosphate (OP) is a prodrug that is readily absorbed from the gastrointestinal tract after oral administration and is extensively converted predominantly by hepatic esterases to Oseltamivir carboxylate (OC)[1]. Oseltamivir phosphate is a widely used anti-influenza sialidase inhibitor. The metabolic activity of CMA07 and CMT-U27 cell lines is significantly decreased with 305 μM Oseltamivir phosphate treatment (p=0.005 and p<0.0001 respectively) using One Way ANOVA testes. In contrast, no statistically significant alterations are observed with 0.305 μM (p=0.9781), 3.05 μM (p=0.7436) and 30.5 μM (p=0.9623) of Oseltamivir phosphate treatments when compare with control cells. Finally, to assess the effect of Oseltamivir phosphate on CMA07 and CMT-U27 programmed cell death, and given that 305 μM Oseltamivir phosphate treatment impaired cell metabolic activity, a programmed cell death measurement is performed with the TUNEL assay. Twenty-four hour Oseltamivir phosphate treatment, specifically at 305 μM, significantly increases CMA07 (p=0.001) and CMT-U27 (p=0.0002) DNA fragmentation, suggesting promotion of programmed cell death, when compare with lower Oseltamivir concentrations, or with PBS[2].In Vivo:Oseltamivir phosphate-treated mice present significantly more inflammatory infiltrate in primary tumors (p=0.01). Ki-67 antigen and caspase-3 protein are used to assess CMT-U27 xenograft tumor cell proliferation and apoptosis respectively. Virtually no differences are found in Ki-67 and caspase 3 (p=0.2) expression between Oseltamivir-treated and non-treated mice[2].

Protocol

Cell Assay [2]
CMA07 and CMT-U27 cells are cultured in 24-well plates in triplicate for each condition: 0.305 μM, 3.05 μM, 30.5 μM and 305 μM Oseltamivir phosphate and PBS is used as control. Cells are counted every day for 7 days in a Neubauer’s chamber in a 1:2 dilution of cells in 0.4% trypan blue and cell count is done using the volume conversion factor for 1 mm3, which is 1×104. This assay is repeated 3 times and growth curves are traced[2].

Animal Administration [2]
Mice[2] Female NIH(S)II-nu/nu nude mice, aged 4-6 weeks, are orthotopically inoculated with 1×106 viable CMT-U27 canine breast cancer cells in the mammary fat pad using a 25 gauge needle. A total of 8 mice are inoculated. When nodules reached a volume of approximately 500 mm3, mice (n=8) are randomized and divided into control group (n=4) and treatment group (n=4).The animals receive intraperitoneally (IP) dailly either 100 μL of PBS (control group) or 100mg/Kg of Oseltamivir phosphate, diluted in PBS (treatment group) until time of death. Tumor size is measured using calipers, and tumor volume (mm3) is estimated by width×length×height.
