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 SIGLEC7 Protein, His Tag PME100645

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

Specifications

size	10µg / 50µg / 100µg

Alternative names:

AIRM-1;AIRM1;CD328;CDw328;D-siglec;p75;p75/AIRM1;QA79;SIGLEC-7;SIGLEC19P;SIGLECP2

Description:

Recombinant human SIGLEC7 protein with C-terminal 6×His tag

Background:

Putative adhesion molecule that mediates sialic-acid dependent binding to cells. Preferentially binds to alpha-2,3- and alpha-2,6-linked sialic acid. Also binds disialogangliosides (disialogalactosyl globoside, disialyl lactotetraosylceramide and disialyl GalNAc lactotetraoslylceramide). The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface. In the immune response, may act as an inhibitory receptor upon ligand induced tyrosine phosphorylation by recruiting cytoplasmic phosphatase(s) via their SH2 domain(s) that block signal transduction through dephosphorylation of signaling molecules. Mediates inhibition of natural killer cells cytotoxicity. May play a role in hemopoiesis. Inhibits differentiation of CD34 cell precursors towards myelomonocytic cell lineage and proliferation of leukemic myeloid cells (in vitro).[UniProtKB/Swiss-Prot Function]

Molecular characterization:

SIGLEC7(Gln19-Leu353) 6×His tag

Molecular weight:

The protein has a predicted molecular mass of 38.6 kDa after removal of the signal peptide. The apparent molecular mass of SIGLEC7-His is approximately 55-70 kDa due to glycosylation.

Tag:

C-6×His Tag

Expression host:

HEK293

Target:

SIGLEC7

Purity:

The purity of the protein is greater than 85% 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.
