PEGylated Liposomal Sulfate

What it means: 200 mM ammonium sulfate — 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 liposomes contain 200 mM ammonium sulfate inside.

Tip: Include empty liposomes or free cargo as controls to separate liposome effects from cargo effects.

What it means: 6 mg/ml — the total lipid concentration of the suspension.

Why it matters:

• Lipid concentration tells you how much liposome material you add per volume.
• It is the basis for calculating doses and lipid-to-cargo ratios.
• Knowing it helps you dilute liposomes to a target lipid amount.
• It allows comparison between liposome preparations.
• Stating the value makes your methods easy to report and repeat.
• Dilution changes the lipid concentration but not the composition.
• Lipid amount is often used to normalize doses between liposome preparations.
• A known lipid amount helps when you compare uptake or release between preparations.

For this product: The suspension contains 6 mg/ml lipid in 0.1 M NaCl.

Tip: Keep the external solution the same when you dilute the liposomes.

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.
