New Products

Abgent develops 1000+ new products per year. We provide tools for path-breaking research by developing antibodies that detect a comprehensive library of novel and established targets. For established targets we seek to add antibodies that recognize new epitopes, including post-translational modifications such as phosphorylation and methylation. For new targets we consult with leading experts to accelerate development of antibodies that will propel state-of-the-art research in cellular health and disease.

Peptides

SARS Peptides

Individual peptides for SARS-CoV-2 Spike glycoprotein. In order to study the specificity of cellular immune responses against SARS CoV-2 and potential immunity caused by other human Corona Viruses, Abcepta provides Spike peptide individually, as pools and in plate. These peptides can be used for antigen specific T-cell stimulation in T-cell assays or T-cell expansion.

Cell/Tissues/Lysates

Abcepta's portfolio of cell lines, tissues and lysates are drawn from a range of species and immortalized cell lines. All our cell lines and lysates are validated in key applications.

These tissue lysates can be used in applications such as SDS-PAGE and Western blotting. Whole cell lysates can be used as positive controls for applications such as ELISAs, immunoprecipitation (IP) and Western blotting. Obtaining high-quality whole cell lysates can be tedious as well as time consuming. Abcepta offers a comprehensive portfolio of whole cell lysates for research use. Browse our catalog to find the right whole cell lysate for your experiment.

Synonyms	CXCL4, SCYB4
Function	Chemokine released during platelet aggregation that plays a role in different biological processes including hematopoiesis, cell proliferation, differentiation, and activation (PubMed:29930254, PubMed:9531587). Acts via different functional receptors including CCR1, CXCR3A or CXCR3B (PubMed:18174362, PubMed:29930254). Upon interaction with CXCR3A receptor, induces activated T-lymphocytes migration mediated via downstream Ras/extracellular signal-regulated kinase (ERK) signaling (PubMed:18174362, PubMed:24469069). Neutralizes the anticoagulant effect of heparin by binding more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Plays a role in the inhibition of hematopoiesis and in the maintenance of hematopoietic stem cell (HSC) quiescence (PubMed:9531587). Chemotactic for neutrophils and monocytes via CCR1 (PubMed:29930254). Inhibits endothelial cell proliferation. In cooperation with toll-like receptor 8/TLR8, induces chromatin remodeling and activates inflammatory gene expression via the TBK1-IRF5 axis (PubMed:35701499). In addition, induces myofibroblast differentiation and collagen synthesis in different precursor cells, including endothelial cells, by stimulating endothelial-to-mesenchymal transition (PubMed:34986347). Interacts with thrombomodulin/THBD to enhance the activation of protein C and thus potentiates its anticoagulant activity (PubMed:9395524).
