SLC5A5 - HEK293 Recombinant Cell line

What it means: The parental cell line is the host in which the transgene or reporter was stably integrated. HEK293 (Human Embryonic Kidney 293) is a epithelial-like, adherent cell line selected for this product.

Why it matters:

• Enables high transfection efficiency and robust transgene expression; widely used for receptor pharmacology, ion channels, and reporter gene assays.
• The parental background determines endogenous receptor expression, growth properties, and media requirements—verify compatibility with your assay conditions.
• Secondary reagents (antibodies, growth media) should be validated for this host species and cell type.

How to interpret here: This product is engineered on a HEK293 background. Pathway activity readouts, IC50/EC50 values, and control responses are calibrated for this host. Results may differ in alternative cell backgrounds.

What it means: Species refers to the biological origin of the expressed gene or protein target in this cell line. This product is classified as Human origin.

Why it matters:

• The transgene or expressed protein is of human sequence. This maximizes compatibility with human-specific antibodies, human interactome databases, and clinically relevant pathway contexts.
• Species origin directly affects antibody cross-reactivity, functional assay interpretation, and translational relevance of results.
• Confirm that your detection antibodies, assay controls, and signaling reagents are validated for Human targets.

How to interpret here: The Human designation indicates the sequence and biological context of the expressed construct—not necessarily the host cell species. Check the host cell line chip for the cellular background.

What it means: BSL-2 (Biosafety Level 2) indicates this material poses moderate risk and requires specific containment practices and training.

Why it matters:

• Work must be performed in a certified BSL-2 laboratory; access is restricted to trained personnel.
• All procedures generating aerosols or splashes must be conducted in a Class II Biological Safety Cabinet (BSC).
• PPE required: lab coat, gloves, and eye/face protection. Decontaminate all waste before disposal.
• Institutional Biosafety Committee (IBC) approval is required prior to use.

How to interpret here: BSL-2 classification means your facility must be BSL-2 certified and your team trained for BSL-2 handling before working with this product. Confirm current IBC approval status and maintain a decontamination log.

Tip: If you are uncertain whether your laboratory is BSL-2 certified, contact your institutional Environmental Health & Safety (EH&S) office.

What it means: Recombinant Cell Line. A Recombinant Cell Line stably expresses a heterologous gene of interest in the host cell background at defined levels confirmed by molecular characterization.

Why it matters:

• Stable integration ensures reproducible target expression across passages, eliminating the variability of transient transfection experiments.
• Select the correct product type based on whether your experiment requires overexpression, loss-of-function, pathway reporting, or immune effector function.

How to interpret here: This Recombinant Cell Line expresses the target protein indicated in the product title. Verify protein expression by Western blot or functional assay upon receipt and after extended culture.

What it means: Liquid Nitrogen storage indicates this cell line must be maintained in vapor-phase or liquid-phase liquid nitrogen (≤-130°C) for long-term preservation of viability and function.

Why it matters:

• Liquid nitrogen cryopreservation halts cellular metabolism and ice crystal formation, preserving cell viability and transgene expression stability for extended periods.
• Storage above -130°C (e.g., -80°C freezer) is not equivalent—cells may lose viability within weeks to months at -80°C.
• Transfer cells from dry-ice shipping to Liquid Nitrogen storage immediately upon receipt to prevent viability loss.

How to interpret here: Liquid Nitrogen storage is required for this product. Access to a liquid nitrogen Dewar or cryogenic storage tank is essential before ordering. Do not store in a standard -80°C freezer as long-term cryostorage.
