Twist Bioscience’s platform is capable of synthesizing thousands of genes each day to meet all your DNA needs. Our silicon-based scalability and high precision oligo production results in high quality DNA synthesis and assembly; qualities that allow Twist to create perfect genes of various lengths and difficulty, NGS-verified and delivered on-time when you need them.

Twist Bioscience Gene Fragments improve your cloning process by minimizing colony screening. This allows you to save time and money by dramatically reducing cloning and sequencing costs. Think bigger, design on a grander scale, and accelerate your discoveries.

Unleash the full power of a well-designed library. With Twist Bioscience, you are assured that the library you design contains the specific modifications, exactly where you want them, saving you valuable resources for the downstream screening process.

The AdEasy system saves you a month of work over traditional methods by producing the recombinant adenoviral plasmid by homologous recombination in E. coli. The AdEasy XL system includes BJ5183 cells pre-transformed with the pAdEasy-1 plasmid, this feature dramatically decreases background caused by the non-recombinant shuttle plasmid.

Recombinant SARS-CoV-2 S1 Subunit Protein with C-terminal His-tag, secreted from the serum-free medium of transfected HEK293 cells. Purchase will also include one vial of normal control (Catalog #. 230-20001), the culture supernatant of HEK293 cell transfected with empty expression vector.

Recombinant SARS-CoV-2, S1 Subunit Protein (RBD) with C-terminal His tag, derived from the transfected human HEK293 cells.

Recombinant monkeypox virus envelope protein H3L with an N-terminal His-tag, derived from E.coli.

Magne™ Protein G and Magne™ Protein A Beads are magnetic affinity beads with high specificity and high capacity for purification of immunoglobulins from cell culture media, ascites and serum samples.   These paramagnetic beads are composed of iron encapsulated in macroporous cellulose with low nonspecific binding. The magnetic beads use a novel attachment chemistry to immobilize recombinant Protein G or Protein A protein…

Recombinant or purified CA19-9 antigen, a sialylated Lewis blood group antigen, which is a widely used serum biomarker for pancreatic and gastrointestinal cancers.

High-purity proteins produced through genetic engineering in heterologous expression systems, ensuring consistency, scalability, and reduced lot-to-lot variability for research and development.

Recombinant Human Programmed Death-Ligand 1 (PD-L1/CD274/B7-H1), the primary ligand for PD-1, expressed on tumor and immune cells to suppress anti-tumor immunity.

Recombinant Human Bone Morphogenetic Protein 7 (BMP-7), a TGF-β superfamily member that induces bone and cartilage formation and plays roles in renal development and repair.

An extensive collection of recombinant Cluster of Differentiation (CD) proteins, which are key cell surface markers for immunophenotyping, immune function studies, and therapeutic targeting.

Recombinant Human Bone Morphogenetic Protein 2 (BMP-2), a key regulatory protein that induces bone and cartilage formation, used extensively in orthopedics and stem cell differentiation.

Recombinant Human Apolipoprotein E (ApoE), a key protein in lipid metabolism that plays a central role in cardiovascular health and Alzheimer's disease pathogenesis.

Recombinant Human B-cell lymphoma 2 (BCL-2) protein, a key regulator of apoptosis (programmed cell death) and a well-established oncoprotein in many cancers.

Recombinant Human B-cell Antigen Receptor Complex-associated protein alpha chain (CD79A), a essential component of the B-cell receptor (BCR) and a marker for B-cell lineage.

A focused set of recombinant immune regulatory proteins, such as PD-1, PD-L1, and CTLA-4, essential for research and drug discovery in cancer immunotherapy and autoimmunity.

Recombinant proteins specifically relevant as E3 ligases or target proteins for Proteolysis Targeting Chimeras (PROTACs), enabling the development of this novel targeted protein degradation technology.

Recombinant Human Fibroblast Growth Factor 2 (Basic FGF), a potent mitogen and morphogen for a wide range of mesoderm and neuroectoderm-derived cells in culture.

Recombinant Human Erythropoietin (EPO), the primary hormone regulating red blood cell production (erythropoiesis), used in research and as a therapeutic for anemia.

Recombinant proteins representing well-validated antigens for Antibody-Drug Conjugates (ADCs), facilitating the screening, characterization, and development of these targeted oncology therapeutics.

Active, stabilized G-Protein Coupled Receptors (GPCRs), prepared in native-like conformations, for high-throughput screening, ligand binding studies, and structure-based drug discovery.

Recombinant Human Programmed Cell Death Protein 1 (PD-1/CD279), a critical immune checkpoint receptor that suppresses T-cell activation and is a major target in cancer immunotherapy.

The Protein A and Protein G Quantification Kits extend the Amperia™ Protein Quantification System for streamlined measurement of antibodies across subclasses and species. Using Fc capture with an inverse-occupancy format, the kits deliver reproducible titres directly from crude or clarified samples, with up to 320 tests per kit.
