Human iPSC Xeno-Free Growth Medium

What it means: Form describes the physical state the product ships in. Human iPSC Xeno-Free Growth Medium is supplied as Liquid — a ready-to-use medium that requires no reconstitution from powder.

Why it matters:

• A Liquid medium can be used straight from the bottle, so there is no weighing, dissolving or pH adjustment step and no batch-to-batch variation introduced in your own lab.
• It sets the handling requirements: keep the bottle closed, warm only the volume you need, and return the remainder to storage promptly.
• Powdered media and liquid media are not interchangeable in a protocol — check this field before substituting a product from another supplier.

How to interpret here: Liquid means the medium arrives as a sterile solution at the stated package size and is ready for immediate use once equilibrated to culture temperature.

What it means: Storage states the condition that preserves the performance of Human iPSC Xeno-Free Growth Medium over its stated shelf life. For this product: Avoid exposure to light. Store at -20°C for up to 12 months. Once thawed, the medium can be stored at 4°C for up to 2 weeks.

Why it matters:

• Growth factors, serum and antibiotic supplements lose activity fastest when a medium is repeatedly warmed and cooled, so warm only the volume needed for the session.
• Light exposure degrades several common medium components, so keep the bottle in the dark whenever the condition mentions protection from light.
• Storing outside the stated condition invalidates the lot-release data supplied with the product.
• Label the bottle with the date it was first opened so the in-use window is tracked separately from the unopened shelf life.

How to interpret here: follow exactly what this field states — Avoid exposure to light. Store at -20°C for up to 12 months. Once thawed, the medium can be stored at 4°C for up to 2 weeks. — from the moment the shipment is unpacked.

What it means: Shipping is the temperature condition the manufacturer uses to transport Human iPSC Xeno-Free Growth Medium. This product ships on Dry ice.

Why it matters:

• Dry ice keeps supplemented media and their growth-factor components at the intended temperature in transit; arrival condition is part of the product specification.
• Plan for someone to receive and unpack the shipment promptly — a package left on a loading dock loses its cold chain.
• Multi-component kits may arrive in more than one package when their components need different transport temperatures, so check the packing list before assuming a shipment is incomplete.
• Record the arrival condition on receipt: a coolant that has fully sublimated or melted is worth noting before the medium goes into storage.

How to interpret here: expect a Dry ice shipment; move the contents to the stated storage condition immediately on arrival.

What it means: Sterility reports the contamination screening applied to every lot of Human iPSC Xeno-Free Growth Medium. Result for this product: Negative for bacteria, yeast, fungi and mycoplasma.

Why it matters:

• Mycoplasma is invisible under a standard microscope and silently alters proliferation and gene expression — screening it at the medium level removes one entry route.
• A documented sterility result lets you attribute a contamination event to handling rather than to reagent quality.
• Sterile filtration does not make a medium sterile forever: aseptic technique on opening still applies.
• Keep the lot number with your culture records so a contamination investigation can be traced back to a specific bottle.

How to interpret here: Negative for bacteria, yeast, fungi and mycoplasma. is the release criterion for the lot you receive, not a guarantee for the medium once the bottle has been opened.

What it means: Cell Type is the cell population this medium was formulated and tested for. Human iPSC Xeno-Free Growth Medium is intended for iPSC.

Why it matters:

• Media are optimised per cell type: the growth-factor and serum composition that supports iPSC cultures will often not support an unrelated lineage.
• Matching the medium to the cell type is the single largest determinant of plating efficiency and passage number in primary culture.
• If you are co-culturing two lineages, check both media before choosing one for the shared well, and validate the compromise on a small plate first.
• Cell-type mismatch usually shows up as poor attachment, flattened morphology or an early growth plateau rather than as outright cell death.

How to interpret here: use this medium for iPSC; for a different lineage, select the medium formulated for that cell type.
