MARCH 2018

KACTUS is Founded

KACTUS embarked on its journey to deliver innovative recombinant proteins solutions, addressing the unmet demands of researchers and the challenges posed by complex protein expression.

JULY 2018

First to express Claudin 18.2

We became the first company to successfully express full-length multi-transmembrane protein Claudin 18.2. This showcased the robustness of our protein engineering capabilities.

2019

SAMS™ Technology Platform

After successfully expressing complex proteins including MHCs and transmembrane proteins, we conceptualized our structure-based protein expression platform, Structure-Aided Multiplex Screening (SAMS™).

2020

Established GMP Enzyme Enterprise

We established our cGMP-compliant enzyme manufacturing facility in 2021, underscoring our commitment to commercialization solutions. This facility provide a range of GMP-Grade mRNA and gene editing enzymes.

2021

GMP Auditing & DMF Submissions

We passed onsite audits for our GMP-compliant facilities by gene editing and mRNA vaccine clients. In alignment with our commitment to regulatory adherence, we filed Drug Master Files (DMF) for our key GMP enzyme products.

FEBRUARY 2022

Making Products Accessible

Our global operational footprint was expanded to include additional warehouse sites, international distributors, ready-to-ship products, and fast shipping speeds. Quality customer service is at the forefront of our logistics operations.

DECEMBER 2022

GMP Enzyme in Clinical Trial

Our GMP-Grade CRISPR Cas9 Enzyme was approved for use in Reforgene Medicine's clinical trial to treat beta-thalassemia, standing as a testament to the credibility of our GMP production facilities and regulatory support.

NOVEMBER 2023

First Commercial Base Editor

KACTUS proudly announced the global release of AccuBase®, the first commercially-available base editor, revolutionizing precision gene editing with unparalleled accuracy and efficiency.

JULY 2024

Expanding Membrane Proteins

We expanded our transmembrane protein display platforms to include nanodiscs, allowing our customers to better overcome membrane protein display challenges.

TODAY

Fueled by Purpose

Today, our solutions have expanded to 3000+ recombinant proteins, 25+ GMP enzymes, and custom protein expression. We continue to launch new products and services that focus on current challenges in R&D and commercialization.

     

Empowering your research with expert protein and enzyme solutions

Elevating protein science with advanced expression

SAMS™ Technology Platform

Our products are developed using our proprietary engineering platform, SAMS™: Structure Aided Multiplex Screening. With this structure- and expression-based platform, we have produced difficult-to-express targets such as full-length CCR8 and Claudin 18.2.

Advantages of SAMS™

Design Expertise

Our expertise in structural biology, protein design, and enzymatic studies, along with our SAMS™ platform, will help you create a protein configuration that will be functional for your application while also optimizing purity & yield.

Tailored Expression Systems

After generating 3D models of your protein/enzyme, we test the configurations in various expression systems to optimize protein folding, maximize bioactivity, and enhance stability.

Quality Bulk Supply

We'll take your protein configuration from bench to large-scale production. Our quality control systems ensure batch-to-batch consistency and our facilities are prepared for consistent high-quantity production.
