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.

	HIP2
Introduction
HIP2 or Ubiquitin-conjugating enzyme E2 K is a protein that in humans is encoded by the UBE2K gene. UBE2K belongs to the ubiquitin-conjugating enzyme family: it accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. It was shown to mediate the selective degradation of short-lived and abnormal proteins, such as the endoplasmic reticulum-associated degradation (ERAD) of misfolded lumenal proteins. HIP2 is expressed in all tissues but has high levels in brain, especially in cortex and striatum and at lower levels in cerebellum and brainstem. HIP2 was shown to bind selectively to a large region at the N terminus of huntingtin protein leading to its proteasomal degradation (see stage 4 in molecular model). Dysfunction of HIP2 activity causes inhibition of proteasome activity and intraneuronal accumulation of ubiquitin conjugates. Consequently, HIP2 is implicated in toxicity of neurodegenerative disorders.	Fluorescent image of Hela cell stained with HIP2 Antibody (Center) (Cat#AP2114c/SH030911H). Hela cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.1%, 10 min), then incubated with HIP2 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). HIP2 is localized to cytoplasm.
