DIMA Biotech

DIMA Biotechnology Ltd. is a biotech company focusing on preclinical R&D products and services for druggable targets. They plan to complete the preparation of lead antibody molecules for all druggable targets in the next 3-5 years. DIMA Biotech provides multiple pre-prepared lead antibody molecules for each target to help pharmaceutical companies skip the tedious steps of monoclonal antibody platform establishment and lead molecule screening. Therefore, companies can have more time to focus on the biological mechanism and developability study of drug targets, thus accelerating the process of new drug R&D.

Over the years, DIMA Biotech has been deeply engaged in developing and optimizing the underlying technology platforms for preclinical research. Currently, they have established two independently developed core technology platforms:

Single/multiple transmembrane protein eukaryotic expression, preparation and purification platforms, apply mammalian cell expression systems, provide ECD or full-length membrane protein products closest to native conformation and functional validation. In addition, DIMA Biotech has developed five major functional full-length transmembrane protein preparation systems, including Membrane Nanoparticle (MNP), Virus-Like Particle (VLP), Exosome (EXO), Detergent and Synthetic Nanodisc. Thousands of drug target protein products are in stock.
DimAb® High-throughput single B-cell lead antibody molecule discovery platform. DIMA Biotech has completed the preparation and screening of lead antibody molecules against more than 200 drug targets by this platform in just two years. Moreover, they have formed strategic partnerships with several international pharmaceutical enterprises and licensed several drug target molecules. DIMA’s preclinical development strength is widely recognized by the industry.

Human CD3D Protein, His Tag and Human CD3E Protein, hFc Tag PME100730

The add to cart button will appear once you select the values above

Specifications

size	10µg / 50µg / 100µg

Alternative names:

CD3-DELTA;IMD19;T3D and IMD18;T3E;TCRE

Description:

Recombinant Human CD3D Protein with C-terminal 6×His tag and Human CD3E Protein with C-terminal human Fc tag

Background:

T-cell surface glycoprotein CD3 delta and CD3 epsilon chain, also known as CD3D and CD3E or CD3DandCD3E respectively, are single-pass type I membrane proteins. CD3D, together with CD3- epsilon(CD3E) , CD3-gamma and CD3-zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T cell receptor-CD3 complex. T cell receptor-CD3 complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways.

Molecular characterization:

CD3D(Phe22-Ala105) 6×His tag and CD3E(Asp23-Asp126) hFc(Glu99-Ala330)

Molecular weight:

The protein has a predicted molecular mass of 10.4 and 37.9 kDa after removal of the signal peptide. The apparent molecular mass of CD3D-His and CD3E-hFc is approximately 35-55 kDa due to glycosylation.

Tag:

C-6×His Tag and C-Human Fc Tag

Expression host:

HEK293

Target:

CD3E

Purity:

The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining.

Formulation / Reconstitution:

Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8% trehalose is added as protectants before lyophilization. Please see Certificate of Analysis for specific instructions of reconstitution.

Storage:

Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature.
