Human
Antigens

As a company we began with the production of high quality human antigens. Over the years the number of natural and recombinant antigens has grown to meet the needs of our customers.

Viral Antigens*

Rotavirus

Rotaviruses are a major etiologic agent in diarrheal illness in infants and young children and a major cause of gastroenteritis.

NF3008 strain: SA11, in glycine buffer $100/mg

Varicella Zoster Virus (VZV)

VZV is similar to herpes simplex virus. It often establishes latent infections in the sensory nerve ganglia. It can cause infection of the skin, vital viscera, mucous membranes and nervous system.

NF0501 negative control, in glycine buffer $15/mg
NF0508 strain: Ellen, in glycine buffer $100/mg

Adenovirus Type 2

Adenoviruses compose a large group of viruses that infect many different species. They cause acute upper and lower respiratory diseases and epidemic conjunctivitis.

NF0908 strain: adenoid 6, in glycine buffer $100/mg

Cytomegalovirus (CMV)

CMV is a subgroup of herpesvirus which has many species-specific strains. Primary infection by human CMV establishes latent and persistent infection.

NF0301 negative control, in glycine buffer $15/mg
NF0308 in glycine buffer $50/mg
NF0325 nuclear extract, in phosphate buffered saline $100/mg
NF0340 nuclear extract, in glycine buffer $100/mg

Herpes Simplex Virus Type 1

HSV1 typically causes vesicular lesions in the oral mucosa but may involve other sites. The use of type-specific antigens can be used to serotype individuals.

NF0101 negative control, in glycine buffer $15/mg
NF0108 strain: MacIntyre, in glycine buffer $50/mg
NF0108F strain: F, in glycine buffer $50/mg

Herpes Simplex Virus Type 2

HSV2 typically causes vesicular lesions in the genital mucosa but may involve other sites. The use of type-specific antigens can be used to serotype individuals.

NF0201 negative control, in glycine buffer $15/mg
NF0208 strain: G, in glycine buffer $50/mg
NF0208A strain: G, in glycine buffer $100/mg

Respiratory Syncytial Virus (RSV)

RSV is a common respiratory virus that usually causes mild cold-like symptoms but can be life threatening in children younger than one year of age.

NF1508 strain: G, in glycine buffer $50/mg

Influenza Virus Strain: A

Influenza A is highly contagious, causes acute respiratory illness and has many different substrains.

NF2848 A/New Caledonia/20/99 (H1N1), in allantoic fluid $100/mg
NF2851 A/Wyoming/03/03, in allantoic fluid $100/mg
NF2852 A/Wellington/01/04 (H3N2) , in allantoic fluid $100/mg
NF2850 A/NY/55/04 X PR8 X-157 R-H3, in allantoic fluid $100/mg

Influenza Virus Strain: B

Influenza B is highly contagious, causes acute respiratory illness and has several different substrains.

NF2849 B/Jiangsu/10/03 , in allantoic fluid $100/mg

Measles Virus

Measles is highly contagious. It is characterized by fever, coryza, cough, conjunctivitis and a generalized rash. Primary infection produces life-long immunity.

NF0601 negative control, in glycine buffer $15/mg
NF0608 strain: Edmonston, in glycine buffer $100/mg

Mumps Virus

The mumps virus causes salivary gland infections (parotitis). Although the virus has mostly been suppressed through the use of vaccines in most affluent countries, it is still relatively common in developing nations.

NF0701 negative control, in glycine buffer $15/mg
NF0708 strain: Jeryl Lynn, in glycine buffer $100/mg
NF070804 strain: Ender’s, in glycine buffer $100/mg
NF078904 strain: Ender’s, Nucleocapsid, in phosphate buffered saline $600/mg

Reovirus Type 3

Reoviruses are a small group of animal viruses. They commonly infect the gastrointestinal and respiratory tracts. They are not generally associated with any specific disease or illness.

NF2908 strain: Abney, in glycine buffer $50/mg

Dengue Virus

There are four known serotypes of dengue. Acquired immunity to one extends only partial and temporary immunity to the others. Symptoms include severe fever, conjunctival congestion, nausea, vomiting and hemorrhagic fever.

NF5111 serotype 1, in phosphate buffered saline $200/mg
NF3211 serotype 2, in phosphate buffered saline $200/mg
NF5011 serotype 3, in phosphate buffered saline $200/mg
NF5211 serotype 4, in phosphate buffered saline $200/mg

West Nile Virus

West Nile Virus is a flavivirus which is spread from mosquitos to humans. Typical symptoms include mild fever, head and body aches, and generalized myalgia with serious infections causing encephalitis and neuronal degeneration.

NF2411U Uganda Strain, in phosphate buffered saline $200/mg
NF2411N New York Strain, in phosphate buffered saline $200/mg

Zika Virus

Zika is a flavivirus and symptoms include severe fever, hemorrhage, conjunctival congestion, nausea and vomiting. Pregnant woman can spread zika to their baby potentially resulting in microcephaly and other birth defects.

NF6308, in glycine buffer $200/mg

* For all viral antigens, infected cells are sonicated and centrifuged to remove insoluble materials.
