Choose ProMab for an Elevated R&D Experience

Cellular engineering & gene delivery systems are going to change the world.

Replacing traditional viral vector gene delivery methods with an mRNA delivery system is a smart alternative for generating transient gene expression in immune cells.

As you strive to bring these new treatments to the market, ProMab can streamline your efforts with ready-to-use mRNA-LNP products and our mRNA-LNP services. Our validated LNP delivery system enables reliable gene delivery to a range of cell types—including T cells, NK cells, macrophages, dendritic cells, and the other prevalent immune cell subtypes—and can include mRNA design, production, formulation, encapsulation, validation, and scale up.

For researchers taking mRNA-LNP applications to the next level, we offer a critical trio of capabilities that no other vendor can provide, custom antibody generation, CAR-T/NK cell development, and mRNA-LNP services. By combining these three capabilities, you can use mRNA-LNPs to turn tumor cells into cancer vaccines, manufacture antibodies in the body, and build truly allogeneic cell therapies because you can alter the cell in the body.

The future of medicine is in your hands. We are excited to join you at the cutting edge.

How It Works

Hand your mRNA synthesis over to experts with a proven high-throughput in vitro transcription workflow.


mRNA production and validation

We give you confidence in our mRNA delivery system with assurance by electroporation.


Formulation of lipid nanoparticles for mRNA delivery

We streamline the formulation of lipid nanoparticles for mRNA delivery with our built-in validation steps.


Optional LNP delivery services

Enjoy a wide range of other services, including mRNA-LNP scale-up and validation for a range of LNP delivery applications.

See The Quality Of Our LNP Delivery Platform


With our mRNA-LNP delivery platform, we can achieve transient gene expression in multiple cell types. This short-term gene expression delivered to targeted sites has essential advantages for reducing unwanted side effects in the body.


Our proven transfection stability, both with regular stability at 4℃ and through freeze-thaw cycles, enables us to provide resilient cells transfected with ProMab mRNA and delivered via ProMab LNPs.

Use mRNA-LNP Delivery For NK Cell Engineering


CAR-encoding mRNAs are efficiently delivered to and expressed in NK cells using a CAR+ mRNA-LNP construct designed and manufactured by the experienced team at ProMab. Left: Non-transfected NK cell control. Right: NK cell + LNP-CAR formulation. Y-Axis: CAR expression.

Use mRNA-LNP Delivery For T Cell Engineering

CAR-encoding mRNAs are efficiently delivered to and expressed in T cells using a CAR+ mRNA-LNP construct designed and manufactured by the experienced team at ProMab. Left: Non-transfected T cell control. Middle: T cell + LNP-CAR formulation detected by mouse Fab'2-APC #1 (Y-axis). Right: T cell + LNP-CAR formulation detected by mouse Fab'2-FITC #2 (X-axis).

Use mRNA-LNPs To Deliver Bispecific Antibodies In Vivo For Anticancer Therapeutic Development

ProMab’s mRNA delivery system transfects cancer cell lines with EpCAM-CD3-hFc mRNA-LNPs, enabling the cells to produce functional antibodies with high antitumor efficacy in vivo. Left: OVCAR-5 cancer cell lines secrete functional EpCAM-CD3-hFc antibody after mRNA-LNP transfection. Middle: EpCAM-CD3-hFc mRNA-LNP-treated T cells significantly decrease tumor growth. Right: Tumor size and weight are significantly decreased with EpCAM-CD3-hFc mRNA-LNP-treated T cells.
