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.

Function
Key decatenating enzyme that alters DNA topology by binding to two double-stranded DNA molecules, generating a double-stranded break in one of the strands, passing the intact strand through the broken strand, and religating the broken strand (PubMed:17567603, PubMed:18790802, PubMed:22013166, PubMed:22323612). May play a role in regulating the period length of BMAL1 transcriptional oscillation (By similarity).
Expressed in the tonsil, spleen, lymph node, thymus, skin, pancreas, testis, colon, kidney, liver, brain and lung (PubMed:9155056). Also found in high-grade lymphomas, squamous cell lung tumors and seminomas (PubMed:9155056)

Application Protocols
Provided below are standard protocols that you may find useful for product applications.
This gene encodes a DNA topoisomerase, an enzyme that
controls and alters the topologic states of DNA during
transcription. This nuclear enzyme is involved in processes such as
chromosome condensation, chromatid separation, and the relief of
torsional stress that occurs during DNA transcription and
replication. It catalyzes the transient breaking and rejoining of
two strands of duplex DNA which allows the strands to pass through
one another, thus altering the topology of DNA. Two forms of this
enzyme exist as likely products of a gene duplication event. The
gene encoding this form, alpha, is localized to chromosome 17 and
the beta gene is localized to chromosome 3. The gene encoding this
enzyme functions as the target for several anticancer agents and a
variety of mutations in this gene have been associated with the
development of drug resistance. Reduced activity of this enzyme may
also play a role in ataxia-telangiectasia.
