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.

	OAT
Introduction
Ornithine aminotransferase (OAT) is a mitochondrial matrix enzyme that is the primary catabolic enzyme for the non-protein amino acid ornithine. It catabolizes ornithine to glutamate or proline (see model below). Ornithine is an important component of the urea cycle, which is responsible for reducing the nitrogen burden in the body by removing the toxic ammonia formed as a result of amino acid catabolism from the body by converting it to urea. Deficiency of ornithine aminotransferase in humans results in gyrate atrophy of the choroid and retina (GA), an autosomal recessive disorder characterized by ornithine accumulation and a progressive chorioretinal degeneration of unknown pathogenesis. OAT is a key mitochondrial enzyme in the pathway that converts arginine and ornithine into the major excitatory and inhibitory neurotransmitters glutamate and GABA.	Fluorescent image of A549 cell stained with OAT Antibody (N-term) (Cat#AP8897a/SA100310AG). A549 cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.1%, 10 min), then incubated with OAT primary antibody (1:25, 1 h at 37°C). For secondary antibody, Alexa Fluor® 488 conjugated donkey anti-rabbit antibody (green) was used (1:400, 50 min at 37°C). Cytoplasmic actin was counterstained with Alexa Fluor® 555 (red) conjugated Phalloidin (7units/ml, 1 h at 37°C). OAT is localized to mitochondrion.
