GenJet™ In Vitro DNA Transfection Reagent for B16-F10 Cells

What it means: The Transfection Type is DNA Transfection: the reagent is formulated for plasmid DNA delivery into cultured mammalian cells. DNA Transfection reagents complex with the plasmid and carry it across the cell membrane so the encoded gene can be expressed.

Why it matters:

• DNA Transfection supports transient expression and, with antibiotic selection, stable cell lines
• Plasmid quality and the DNA-to-reagent ratio are the main drivers of efficiency
• Reporter, overexpression and CRISPR plasmids are all delivered the same way
• Vendor stated yield: One milliliter of GenJet™ Reagent is sufficient for approximately 300–600 transfections in 24-well plates or 150–300 transfections in 6-well plates, depending on the culture format and amount of DNA used

How to interpret here: Use this DNA Transfection reagent for plasmid work; for siRNA or miRNA choose an siRNA Transfection reagent from the same family.

Tip: Include a reporter plasmid such as GFP in the first DNA Transfection to check efficiency before committing the experimental construct.

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 B16-F10: the vendor pre-optimized this formulation and protocol for B16-F10 cells. The B16-F10 line is a highly metastatic murine melanoma, derived from the B16 melanoma that was first established in C57BL/6 mice, and laboratories turn to it routinely as an experimental model in melanoma biology, tumor metastasis, cancer immunology, and work on novel anticancer therapies. Several melanoma-associated antigens are expressed by these cells — tyrosinase and the tyrosinase-related proteins TRP-1 and TRP-2 among them, alongside other tumor-associated antigens — which makes the line a valuable platform for evaluating cancer vaccines, immunotherapies, and gene-based therapeutic approaches.

Why it matters:

• The optimization panel normally run for a new cell type is not needed for B16-F10
• Results in B16-F10 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 B16-F10 cells; for another cell line choose the matching pre-optimized version or the general-purpose reagent.

Tip: The B16-F10 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. When maintained under the recommended storage conditions, the product remains stable for at least 24 months. 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.
