| Additional Infomation |
Ceftiofur sodium is an organic molecular entity. Ceftiofur sodium is the sodium salt form of ceftiofur, a semi-synthetic, β-lactamase-stable, broad-spectrum third-generation cephalosporin with antibacterial activity. Ceftiofur binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of bacterial cell walls. PBPs are enzymes involved in the final stages of bacterial cell wall assembly and in remodeling the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linking of peptidoglycan chains, which is essential for maintaining the strength and rigidity of bacterial cell walls. This leads to weakening of the bacterial cell wall and cell lysis. See also: Ceftiofur (containing the active ingredient). Indications: Swine: Treatment of bacterial respiratory diseases caused by Actinomyces pleuropneumoniae, Pasteurella multocida, Haemophilus parasuis, and Streptococcus suis. Treatment of septicemia, polyarthritis, or polyserositis caused by Streptococcus suis infection. Cattle: Treatment of acute interdigital necrosis (also known as hoof rot) in cattle. Treatment of acute postpartum (puerperal) metritis in cattle, applicable when other antimicrobial treatments are ineffective.

| Solubility (In Vitro) |
DMSO : ~50 mg/mL (~91.65 mM)

|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: 1.67 mg/mL (3.06 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 16.7 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 1.67 mg/mL (3.06 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 16.7 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 1.8330 mL | 9.1652 mL | 18.3305 mL | |
| 5 mM | 0.3666 mL | 1.8330 mL | 3.6661 mL | |
| 10 mM | 0.1833 mL | 0.9165 mL | 1.8330 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
