Anti-BCMA CAR /NFAT (Luciferase) Reporter Jurkat Cell Line

What it means: The parental cell line is the host in which the transgene or reporter was stably integrated. Jurkat (clone E6-1) (specialized host) is a adherent or suspension cell line selected for this product.

Why it matters:

• Enables consistent transgene expression in a characterized background.
• 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 Jurkat (clone E6-1) 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-1 (Biosafety Level 1) indicates this agent is not known to cause disease in healthy adults and poses minimal risk to laboratory personnel and the environment.

Why it matters:

• Standard microbiological practices apply; no special containment facility is required beyond a clean bench.
• Routine PPE (gloves, lab coat, eye protection) and hand-washing protocols are sufficient.
• Institutional Biosafety Committee (IBC) registration may still be required for genetically modified organisms—consult your IBC before use.

How to interpret here: BSL-1 means this cell line can be handled on an open bench in a standard laboratory. Check your institution's IBC policy, particularly if the construct contains a selectable antibiotic resistance marker or modified genetic elements.

What it means: CAR-T Cell Line. A CAR-T Cell Line stably expresses a Chimeric Antigen Receptor (CAR) construct in a T cell background, enabling functional assays for immune cell activation and cytotoxicity.

Why it matters:

• Enables standardized, reproducible effector cell assays for immunotherapy research without the donor variability of primary T cells.
• 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 CAR-T Cell Line expresses the CAR construct specified in the product title. Use the recommended target cell (antigen-positive) and control cell lines for accurate effector-to-target ratio experiments.

What it means: Confirmed Negative indicates this cell line was screened using a validated mycoplasma detection assay prior to release and confirmed negative for mycoplasma contamination.

Why it matters:

• Mycoplasma contamination can significantly alter gene expression profiles, proliferation rates, metabolism, and assay readouts—potentially invalidating experimental results without visible signs of contamination.
• Testing prior to use is considered best practice in accordance with ATCC and ECACC guidelines for cell line authentication.
• BPS Bioscience uses validated PCR-based or luminescence-based detection kits (e.g., Venor™GeM, MycoAlert™) for screening.

How to interpret here: Confirmed Negative confirms the product shipped to you passed mycoplasma screening at the time of manufacture. We still recommend performing routine mycoplasma testing in your laboratory after receipt and during extended culture to confirm ongoing negative status.

Tip: Test your cell cultures for mycoplasma at regular intervals (e.g., every 2–4 weeks) regardless of the vendor QC status. Contamination can be introduced during routine culture handling.

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.
