Datasheet of Efaproxiral sodium
Description:. Efaproxiral, a synthetic allosteric modi?er of hemoglobinoxygen binding af?nity, has been shown to bind reversibly to hemoglobin, stabilizing the deoxyhemoglobin tetramer conformation to reduce its af?nity for oxygen. Efaproxiral plus oxygen breathing reduces the radiobiological hypoxic fraction of EMT6 tumors from the value of 24% found in both air-breathing and oxygen-breathing mice to 9% and improves the response of the tumors to radiation. Carboplatin (100 mg/kg) slowes tumor growth in air-breathing mice, producing a growth delay of 3.3 days. Efaproxiral plus oxygen increases the growth delay to 5.7 days; this is 2.4 days (71%) greater than that for carboplatin alone and 2.1 days (57%) greater than that for carboplatin plus oxygen breathing. Efaproxiral plus oxygen breathing, therefore, improves the tumor growth delay obtained with 100 mg/kg carboplatin to or beyond that obtained with the highly toxic dose of 150 mg/kg carboplatin, but does so without increasing the toxicity beyond that seen with 100 mg/kg carboplatin in air-breathing mice. Efaproxiral significantly increases tumor oxygenation by 8.4 to 43.4 mmHg within 5 days in C3H mice with RIF-1 tumors, with maximum increases at 22-31 min after treatment. Efaproxiral plus oxygen plus Radiation produces tumor growth inhibition throughout the treatment duration in C3H mice with RIF-1 tumors, and inhibition is significantly different from radiation plus oxygen from day 3 to day 5.

Storage
Store at -20°C (desiccating conditions).
Handling: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months. Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
