GenMute™ siRNA Transfection Reagent for Jurkat Cells

What it means: The Transfection Type is siRNA Transfection: the reagent is formulated for small RNA cargo such as siRNA and miRNA used in gene knockdown. siRNA Transfection reagents are tuned for short duplex RNA rather than for large plasmids.

Why it matters:

• siRNA Transfection delivers the duplex to the cytoplasm, where the RNAi machinery acts on the target mRNA
• Knockdown is read out as reduced mRNA or protein, usually 24 to 72 hours after transfection
• The siRNA concentration and reagent volume per well are set by the protocol; both affect knockdown and cell health
• Vendor stated yield: A 1.0 mL vial is sufficient for ~833 reactions based on transfecting 10 pmol siRNA or miRNA mimics in a 24-well plate

How to interpret here: Use this siRNA Transfection reagent for RNAi knockdown; for plasmid DNA choose a DNA Transfection reagent from the same family.

Tip: Run a non-targeting control siRNA alongside; it separates the knockdown effect from the effect of siRNA Transfection itself.

What it means: The Application Setting is In Vitro: the reagent is intended for cultured cells in plates, dishes or flasks. An In Vitro setting means the transfection complex is added to the culture medium and taken up by the cells over a few hours.

Why it matters:

• In Vitro protocols are defined per well or plate format, so the reagent volume scales with the culture surface
• Serum, confluence and cell type affect efficiency and toxicity
• Results are read out in the same cells 24 to 72 hours later

How to interpret here: Use this reagent for In Vitro cell-culture transfection; it is not an animal-use product.

Tip: Seed cells the day before so they are 70 to 90 percent confluent and actively dividing at the time of In Vitro transfection.

What it means: The Optimized Cell Line is Jurkat: the vendor pre-optimized this formulation and protocol for Jurkat cells. Much of that research treats the line as a key model: acute T-cell leukemia, signaling through the T-cell receptor, apoptosis, and how chemokine receptors tied to viral entry, HIV among them, are expressed. Interleukin-2 (IL-2) production and immune activation pathways are studied in them as well.

Why it matters:

• The optimization panel normally run for a new cell type is not needed for Jurkat
• Results in Jurkat are more consistent from experiment to experiment when the ratio is fixed
• The same product family is offered pre-optimized for other cell lines

How to interpret here: Pick this version if you work with Jurkat cells; for another cell line choose the matching pre-optimized version or the general-purpose reagent.

Tip: The Jurkat optimization assumes the vendor protocol; if you change plate format or serum, re-check the ratio once.

What it means: Storage is 4 °C. Vendor statement: Store at 4 °C. If stored properly, the product is stable for 24 months or longer. The Storage condition is the temperature the vendor tested the stability window against.

Why it matters:

• Storage at 4 °C keeps the reagent within the vendor stability window
• Repeated warming and cooling, or freezing when not stated, can reduce transfection efficiency
• A kit with a reagent and a buffer can have two conditions; each component is stored at its own

How to interpret here: Store at 4 °C on receipt and keep the vial closed between uses.

Tip: Let a refrigerated reagent reach room temperature before opening so condensation does not enter the vial.

What it means: Shelf Life is 24 months: the vendor states the product is stable for 24 months or longer when stored as directed. The Shelf Life is a stability statement for the product line, not a lot-specific expiry.

Why it matters:

• A 24 months shelf life lets one vial cover a multi-month project
• Stability applies only under the stated storage condition
• Buying a larger size is practical when the reagent will be used within the 24 months window

How to interpret here: Note the receipt date; 24 months is the vendor stability statement rather than an expiry printed per lot.

Tip: If efficiency drops late in the 24 months window, run the reporter control again before changing other variables.
