Rabbits were immunized with recombinant human coronavirus OC43 spike glycoprotein protein (15-344aa) to generate the CSB-PA321224LA01BUA polyclonal antibody against the spike protein. The spike protein of human coronavirus OC43 is an essential component of the virus and plays a crucial role in its pathogenesis, making it a potential target for the development of vaccines and therapeutics.

Following protein G purification, the rabbit anti-human coronavirus OC43 S polyclonal antibody achieved a purity level of 95%. This non-conjugated IgG specifically binds to the spike protein of human coronavirus OC43 and can detect endogenous levels of the protein, as demonstrated by ELISA.

Applications : Western Blot Assay

Sample type: Cells

Review: Western blot of the lysates of HCoV-OC43-infected MRC-5 cell streated with kurarinone or vehicle and evaluated at 1,2,3, and 4dpi. The HCoV-OC43 Spike protein was detected and indicated by an arrow head as shown; β-actin was used as a loading control.

By Anonymous

Applications : Immunofluorescence experiments

Sample type: cells

Review: To assess whether 5 min of various UVC illumination reduces the number of infected cells, immunostaining was performed to detect the presence of OC43 viral particles in the host human cells.

By Anonymous

Applications : Western Blot Analysis

Sample type: cell

Review: In MRC-5 and A549 cells was detected using Western blot analysis following HCoV-OC43 infection and vehicle or 10 μM CDN treatment at 1–4 dpi. β-actin was used as the internal control.

Target Background

S1 attaches the virion to the cell membrane by interacting with sialic acid-containing cell receptors, initiating the infection.; attaches the virion to the cell membrane by interacting with host receptor, initiating the infection.; mediates fusion of the virion and cellular membranes by acting as a class I viral fusion protein. Under the current model, the protein has at least three conformational states: pre-fusion native state, pre-hairpin intermediate state, and post-fusion hairpin state. During viral and target cell membrane fusion, the coiled coil regions (heptad repeats) assume a trimer-of-hairpins structure, positioning the fusion peptide in close proximity to the C-terminal region of the ectodomain. The formation of this structure appears to drive apposition and subsequent fusion of viral and target cell membranes.; Acts as a viral fusion peptide which is unmasked following S2 cleavage occurring upon virus endocytosis.
Subcellular Location
