Molecular Weight(MW)
139125 Da
Function
S1 attaches the virion to the cell membrane by interacting with human ACE2 and CLEC4M/DC-SIGNR, initiating the infection. Binding to the receptor and internalization of the virus into the endosomes of the host cell probably induces conformational changes in the S glycoprotein. Proteolysis by cathepsin CTSL may unmask the fusion peptide of S2 and activate membranes fusion within endosomes
Tissue Specificity
This SARS virus Sn antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 13~42 amino acids from the N-terminus of SARS CoV Spike protein.
Cellular Localization
Virion membrane; Single-pass type I membrane protein. Host endoplasmic reticulum-Golgi intermediate compartment membrane; Single-pass type I membrane protein (By similarity) Host cell membrane; Single-pass type I membrane protein Note=Accumulates in the endoplasmic reticulum-Golgi intermediate compartment, where it participates in virus particle assembly (By similarity). Some S oligomers are transported to the plasma membrane, where they may mediate cell-cell fusion
Application
Application
The anti-SARS-Sn Pab is used in Western blot to detect recombinant Spike proteins, aa17-537 (Lane 1) and aa17-756 (Lane 2).

Storage Instructions
For short-term storage, store at 4° C. For long-term storage, aliquot and store at -20ºC or below. Avoid multiple freeze-thaw cycles.
Storage Buffer
Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein G column, eluted with high and low pH buffers and neutralized immediately, followed by dialysis against PBS.
