The Extracellular domain (ECD) is from aa 1 to 1208 (full length 1273aa). Therefore, this antibody detects the transmembrane and cytoplasm domains at the C terminus, but does not detect the ECD (which is the region expressed in many commercially available spike proteins). ab272504 can be used for the detection of full length spike protein and spike protein in COVID-19 patient samples. It will detect 4 ng of free peptide at 1 μg\/mL.\u003c\/p\u003e\n\n\u003cp\u003eProduct details:\u003cbr\u003e\nAnti-SARS-CoV-2 spike glycoprotein antibody - Coronavirus (ab272504) is a rabbit polyclonal antibody and is validated for use in ELISA, ICC\/IF, IHC-P and WB.\u003cbr\u003e\nAnti-SARS-CoV-2 spike glycoprotein antibody - Coronavirus (ab272504) was first used in a scientific publication in 2020 and has been cited over 48 times in peer reviewed journals.

This protein has a molecular weight of approximately 180 kDa and is found on the surface of the virus. It facilitates viral entry into host cells by binding to the angiotensin-converting enzyme 2 (ACE2) receptor. The spike protein consists of two subunits S1 and S2 where S1 contains the receptor-binding domain (RBD) responsible for engaging with ACE2 while S2 mediates viral and host membrane fusion.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThe spike protein serves as a primary target for the host immune response. It is part of the viral envelope complex essential for the virus's infectivity. The spike protein undergoes structural changes during host cell entry transitioning from a prefusion to a postfusion conformation. This ability to change structure is important for facilitating membrane fusion. Anti-spike antibodies such as those found in convalescent plasma and generated by vaccines target this protein aiming to neutralize the virus and prevent infection.\u003cbr\u003e\nPathways\u003cbr\u003e\nThe spike glycoprotein is integral to the viral infection and replication process. The renin-angiotensin system (RAS) pathway plays a significant role as ACE2 a critical component is the entry point for the virus. The spike protein's interaction with ACE2 disrupts the RAS balance leading to potential downstream effects. Additionally the spike protein's role in membrane fusion links it to the endosomal sorting complex pathways necessary for the trafficking of viral particles within host cells.\u003cbr\u003e\nThe spike protein's association with COVID-19 makes it central in understanding disease progression and potential complications. Its interaction with ACE2 is not only significant for viral entry but also links to severe acute respiratory syndrome (SARS) as both viruses exploit this receptor for entry. Moreover the association with inflammatory-related pathways indicates the spike protein's potential in driving cytokine storms which are severe immune responses contributing to the disease’s morbidity. Anti-spike antibodies and therapies are designed to mitigate these effects emphasizing the protein's importance in therapeutic strategies.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46845036298409,"sku":"ab272504","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab272504","provider":"Iright","version":"1.0","type":"link"}
