PEGylated HSPC Liposomal Ciprofloxacin

What it means: HSPC : DSPE-PEG2000 : cholesterol 3 : 1 : 1 — the lipids that form the bilayer.

Why it matters:

• Lipid composition affects membrane rigidity, stability and drug release.
• PEGylated lipids add a polymer layer that changes how liposomes interact with proteins and cells.
• Cholesterol makes the bilayer more stable and less leaky.
• Matching composition to your study makes results easier to compare with published work.
• Stating the composition makes your methods easy to report and repeat.
• The phase transition temperature of the main lipid affects how the bilayer behaves at assay temperature.
• Changing composition between experiments can change results even with the same cargo.

For this product: The bilayer is HSPC : DSPE-PEG2000 : cholesterol 3 : 1 : 1 by mass.

Tip: Compare with the non-PEGylated DPPC version when PEG coating matters for your study.

What it means: 1 mg/ml ciprofloxacin — what is inside the liposomes and at what concentration.

Why it matters:

• The encapsulated cargo defines what the liposome delivers.
• The internal concentration sets how much cargo one volume of liposomes carries.
• Knowing the cargo helps you design the right controls, such as empty liposomes.
• Cargo and lipid composition together decide release behavior.
• Stating the cargo makes your methods easy to report and repeat.
• Liposomes can deliver cargo that would not cross a cell membrane on its own.
• The cargo concentration helps you calculate the dose delivered per volume of liposomes.

For this product: The formulation contains 1 mg/ml ciprofloxacin, more than 95% encapsulated.

Tip: Remove any free drug before release studies if your method requires it.

What it means: Cold, Not Frozen — how the product is shipped.

Why it matters:

• The shipping condition tells you what to expect when the package arrives.
• Unpacking promptly lets you check the contents against the order.
• Checking the package on arrival helps you spot transport problems early.
• Storage conditions can differ from shipping conditions, so confirm them before the package arrives.
• Recording the arrival date and condition helps if questions come up later.
• Arranging for someone to receive the package avoids delays when it arrives.
• The shipping condition is chosen to keep the product as described during transport.

For this product: Ships cold, not frozen. Please contact us to confirm storage conditions.

Tip: Do not freeze liposomes; check the package on arrival and contact us right away if anything is damaged or missing.
