Lasalocid is an ionophore antibiotic.
Lasalocid is produced by Streptomyces lasaliensis and is a mixture of several closely related homologue substances A, B, C, D, E. The sum of the lasalocid homologues B, C, D, E is limited to 10% of the total weight of the active substance, lasalocid.
In vitro: A previous study was conducted to compare effects of the combined use of lasalocid and silybin in chicken hepatoma cells and rat myoblasts cell lines cultures. Results showed that in all performed tests, the lowest lasalocid EC50-values were obtained for chicken hepatocytes. In the rat myoblasts cultures, the lowest lasalocid EC50-values were found. Moreover, a lack of silybin cytotoxic effect was proven for the studied cell lines. An interaction between both substances resulted in a great decrease of lasalocid cytotoxicity. The isobolograms and combination index indicated a significant antagonistic nature of silybin effect in the course of lasalocid cytotoxicity [1].
In vivo: In a animal study, chickens 8 or 9 days old were given a completely purified crystalline amino acid diet. Results showed that the requirement for sulphur-containing amino acids (SAA) was neither increased nor decreased by lasalocid at 125 mg/kg diet. Moreover, lasalocid could cause a significant increase in gain and gain/feed intake when added to diets that were deficient in SAA, but it led to a marked decrease in performance when added to diets adequate in SAA. In addition, at moderate levels of SAA deficiency, lasalocid at 125 mg/kg could neither increase nor decrease the rate and efficiency of weight gain and there was no evidence of the SAA X lasalocid interaction when lasalocid was given in a typical starter diet of maize and soya [2].
Clinical trial: So far, no clinical study has been conducted.

General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
