Stable Cell Lines | CHO & HEK293 Expression

Accelerate your protein production and cell-based assay development with 80+ ready-to-use stable cell lines. Built on CHO and HEK293 platforms using our proprietary XtenCHO™ expression system, each cell line is engineered for high-yield recombinant protein or antibody expression with documented stability over 20+ passages. Fully characterized with expression level, growth curve, and mycoplasma-free certification. All products are designated Research Use Only (RUO) — not intended for diagnostic or therapeutic procedures. RUO

Why Researchers Choose abinScience

XtenCHO™ Proprietary Platform Our CHO-based expression platform delivers optimized glycosylation, high viability, and scalable production — from research-scale to upstream process development.

Ready to Culture Ships as frozen vials with complete recovery protocol. Revival rate ≥90%. No additional cloning or selection required — thaw, expand, and produce.

Fully Characterized Each cell line ships with expression data (ELISA/SDS-PAGE), mycoplasma testing (PCR-negative), growth curves, and recommended culture conditions.

Catalog-to-CRO Upgrade Need a custom target or higher titer? Upgrade seamlessly from catalog cell lines to custom CHO stable cell line development through our AtaGenix CRO services.

How to Select the Right Cell Line

1 Target Protein: Browse by the recombinant protein or antibody you need expressed. Each product page specifies the target gene, expression construct, and expected titer.

2 Host Cell Platform: Choose CHO for therapeutic-relevant glycosylation and regulatory familiarity; HEK293 for fast turnaround and complex proteins requiring human PTMs.

3 Application: For drug screening and functional assays, choose lines expressing the target receptor or ligand. For protein production, select lines with verified high-titer expression.

FAQs

How do I thaw and recover the cell line?

Thaw the vial quickly in a 37°C water bath (~2 minutes), transfer to pre-warmed complete medium, centrifuge to remove DMSO, and resuspend in fresh medium. Detailed recovery protocols are provided with each shipment.

What culture medium is recommended?

Recommended media and supplements are listed on each product datasheet. CHO lines typically use chemically defined, serum-free media. HEK293 lines are maintained in DMEM + 10% FBS unless otherwise specified.

How long is expression stable?

All catalog cell lines are validated for expression stability over ≥20 passages. For long-term use, we recommend banking early-passage cells and monitoring expression periodically by ELISA or western blot.

Can I get a custom stable cell line for my target?

Yes. Through our AtaGenix CRO services, we offer custom CHO and HEK293 stable cell line development — from gene synthesis through single-cell cloning, expression optimization, and cell banking. Contact our team for a project consultation.
