In Vitro

Rifampicin (100 microg/mL) can block the functional activity of P-glycoprotein. Rifampicin is not a substract for P-glycoprotein. The mechanism of rifampicin resistance is unassociated with the functional activity of P-glycoprotein^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Rifampicin (200, 400 mg/kg) can induce fatty liver at high concentration^[1]. Rifampicin (30 mg/kg, i.p.) treatment of S464P biofilms in vivo results in a slight decline, but earlier rebinds in bioluminescence from these catheters compared with the parental signal, whereas rifampicin has no affect on bioluminescence in mice infected with mutant H481Y^[2].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

This protocol yields a clear solution of 2.5 mg/mL.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2.5 mg/mL (3.04 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol

Animal Administration^[2]

Briefly, 1 cm Teflon catheter (14-gauge) carrying 104 cfu S. aureus, either the parental strain Xen 29 or the RifR mutants S464P or H481Y, are implanted subcutaneously in groups of nine mice per strain. One catheter segment is inserted on each side of each animal. Six days after the implantation of the catheters, five mice from each group are treated with rifampicin at 30 mg/kg intraperitoneally in 0.1 mL saline, twice daily for four consecutive days. The remaining four mice in each group are left untreated as controls. At various time points during the infection, the mice are anaesthetized using a constant flow of 1.5% isoflurane from the IVIS^® manifold, and imaged using an IVIS^® Image System 100 Series. The bioluminescent signals (photons/s) emitted from the mice are analysed using LivingImage^® software and plotted over the course of infection. The mice are sacrificed 20 days after infection (11 days after final rifampicin treatment). The catheters are surgically removed and the bacteria are detached by sonication for determination of bacterial burdens on the catheters.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
