HIV1 p24 proteins form viral capsid that encapsulates the genomic HIV1 RNA. HIV1 p24 concentration in host plasma is commonly used as indicator of viral load. Upon the viral infection, the development of anti-HIV1 p24 host humoral responses leads to immune complex formation and reduction of the free HIV1 p24 concentration in circulation.\u003cbr\u003e\nLentivirus vectors based on HIV-1 have gained popularity as a tool for cell and gene therapy, owing to their ability to carry and integrate a high volume of transgenes in a range of dividing and non-dividing cell types. Pseudo-lentiviral particles are typically produced from 293T cells and harvested from the medium 48-78hrs post-transfection. To ensure that the pseudoviral medium is viable, and to control the number of copies of integrated viral constructs per target cell, the viral titre needs to be determined before transduction experiments. Our HIV1 p24 SimpleStep ELISA\u003cbr\u003e\ncan be used to rapidly and sensitively determine the titre of HIV1 particles in range of sample types.\u003cbr\u003e\nREACH authorisation\u003cbr\u003e\nAbcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.\u003cbr\u003e\nIt is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nThe p24 protein also known as the HIV-1 capsid protein or CA is an important component of the Human Immunodeficiency Virus Type 1 (HIV-1). It has a molecular weight of approximately 24 kDa. This protein is expressed in the viral core and plays a critical role in the virus's structural integrity. The p24 protein helps form the conical core that encases the viral RNA genome. Antibody-based detection of this protein is a common approach to study HIV often utilizing tools such as the p24 ELISA kit and p24 assay which are pivotal in early HIV detection and research.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThe p24 protein is essential in the assembly and maturation of the HIV-1 virion. It forms part of the Gag polyprotein precursor which undergoes proteolytic cleavage to create the mature viral proteins necessary for the formation of infectious particles. The Gag polyprotein assembles into the immature virion and later cleaves into functional units including the matrix capsid and nucleocapsid proteins. This process ensures the viral core is capable of delivering the genetic material to the host cell during infection. Such assembly is important for maintaining the infective efficiency of the HIV-1 virus.\u003cbr\u003e\nPathways\u003cbr\u003e\nP24 plays an integral role in the lifecycle of HIV-1 especially in the virus replication and assembly pathways. It interacts with host cellular machinery to facilitate the viral assembly and is involved in the highly coordinated regulation of the viral life cycle. This protein shares pathway connections with other viral proteins such as p55 Gag and matrix protein p17 both of which also derive from the Gag polyprotein. These interactions underline the importance of p24 in the broader context of HIV-1's ability to propagate within host cells.\u003cbr\u003e\nThe p24 protein is directly linked to the pathogenesis of Acquired Immunodeficiency Syndrome (AIDS). Understanding and detecting the presence of p24 are vital for diagnosing and monitoring the progression of HIV-1 infection. Additionally it holds a significant relationship with immune system disorders due to the virus's effect on immune function. p24 detection is often a component in HIV ELISA and HIV p24 ELISA tests which measure the presence of the virus in the bloodstream. The protein also connects to the envelope glycoprotein gp120 which is involved in initial host cell binding and viral entry furthering its pivotal role in the progression of HIV-related diseases.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843611513001,"sku":"ab218268","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab218268","provider":"Iright","version":"1.0","type":"link"}
