Seasonal H1N1 Neuraminidase Antibody
Influenza A virus is a major public health threat, killing more than 30,000 people per year in the USA (1). In early 2009, a novel swine-origin influenza A (H1N1) virus was identified in specimens obtained from patients in Mexico and the United States (2). The virus spread quickly around the world and on June 11, 2009, the World Health Organization declared it a pandemic (3). Influenza A virus has one of sixteen possible Hemagglutinin (HA) surface proteins and one of nine possible neuraminidase (NA) surface proteins. The Hemagglutinin protein facilitates viral attachment while neuraminidase is involved in viral release. These proteins also elicit immune responses that prevent infection or independently reduce viral replication. The genetic make-up of this swine flu virus is unlike any other: it is an H1N1 strain that combines a triple assortment first identified in 1998 including human, swine, and avian influenza with two new pig H3N2 virus genes from Eurasia, themselves of recent human origin (4). The distinct antigenic properties of the new swine influenza virus compared with seasonal influenza A (H1N1) virus suggest that human immunity against new swine influenza virus is limited, although the age distribution of reported cases suggests some degree of protection in older age groups (5). This antibody is specific for Neuraminidase from the seasonal influenza (H1N1) and will not recognize the corresponding Neuraminidase sequence from the swine-origin influenza virus (A/California/14/2009 (H1N1)).
Additional Names : Seasonal Influenza A (H1N1) Neuraminidase Antibody, Seasonal Influenza A (H1N1) Neuraminidase, Influenza N1, flu N1, NA
Left: ELISA results using Seasonal H1N1 Neuraminidase antibody at 1 µg/ml and the blocking and corresponding peptides at 50, 10, 2 and 0 ng/ml.
Source :Neuraminidase antibody was raised against a synthetic peptide from the seasonal influenza (H1N1) Neuraminidase protein. This antibody is a cognate pair with product 5249.
Purification : Affinity chromatography purified via peptide column
Clonality and Clone : This is a polyclonal antibody.
Host : Seasonal H1N1 Neuraminidase antibody was raised in rabbit.
Please use anti-rabbit secondary antibodies.
Application : Neuraminidase antibody can be used for the detection of the Neuraminidase protein from the seasonal influenza A (H1N1) in ELISA. It will detect 2 ng of free peptide at 1 µg/ml and will not cross-react with peptide corresponding to the swine-origin influenza (H1N1) Neuraminidase. Other applications are pending.
Tested Application(s) : E
Buffer : Antibody is supplied in PBS containing 0.02% sodium azide.
Blocking Peptide :Cat.No. 5247P - Seasonal H1N1 Neuraminidase Peptide
Long-Term Storage : Seasonal H1N1 Neuraminidase antibody can be stored at 4ºC, stable for one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.
