18,000+ products cover the ten top research categories, including cancer, metabolism, cardiovascular, neuroscience, and stem cells. Each antibody is crafted with care according to rigorous protocols for immunogen design and preparation, presentation to host animal, and high-affinity purification against the antigen. Quality is embedded in the production process to assure the best antibody for you.
Crown antibodies pass additional stringent quality requirements, including extended control sets, uniform results against multiple biologically relevant cell lines and tissues, and function in multiple applications.
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.
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.
All peptides are manufactured in the San Diego, California. Custom peptide services include long peptides (>100 aa), cyclic peptides, difficult sequences, fluorescent labels, phospho-peptides and other post-translational modifications.
The majority of Abcepta antibodies are produced using peptide immunogens. These immuno-specific peptides can be used as blocking agents when using the complementary antibodies in a range of applications.
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.

Foundational characteristics of cancer include proliferation, angiogenesis, migration, evasion of apoptosis, and cellular immortality. Find key markers for these cellular processes and antibodies to detect them.
The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.
The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.

Protein Information
Name
CD55
Synonyms
CR, DAF
Function
This protein recognizes C4b and C3b fragments that condense with cell-surface hydroxyl or amino groups when nascent C4b and C3b are locally generated during C4 and c3 activation. Interaction of daf with cell-associated C4b and C3b polypeptides interferes with their ability to catalyze the conversion of C2 and factor B to enzymatically active C2a and Bb and thereby prevents the formation of C4b2a and C3bBb, the amplification convertases of the complement cascade (PubMed:7525274). Inhibits complement activation by destabilizing and preventing the formation of C3 and C5 convertases, which prevents complement damage (PubMed:28657829).
Cellular Location
[Isoform 1]: Cell membrane; Single-pass type I membrane protein [Isoform 3]: Secreted [Isoform 5]: Secreted [Isoform 7]: Cell membrane; Lipid-anchor, GPI-anchor
Tissue Location
Expressed on the plasma membranes of all cell types that are in intimate contact with plasma complement proteins. It is also found on the surfaces of epithelial cells lining extracellular compartments, and variants of the molecule are present in body fluids and in extracellular matrix

Application Protocols
Provided below are standard protocols that you may find useful for product applications.
This gene encodes a protein involved in the regulation of
the complement cascade. The encoded glycoprotein is also known as
the decay-accelerating factor (DAF); binding of DAF to complement
proteins accelerates their decay, disrupting the cascade and
preventing damage to host cells. Antigens present on the DAF
glycoprotein constitute the Cromer blood group system (CROM). Two
alternatively spliced transcripts encoding different proteins have
been identified. The predominant transcript encodes a
membrane-bound protein expressed on cells exposed to plasma
component proteins but an alternatively spliced transcript produces
a soluble protein present at much lower levels. Additional,
alternatively spliced transcript variants have been described, but
their biological validity has not been determined. [provided by
RefSeq].
