Recombinant Antigens

Epstein Barr Virus, Early Antigen (D)

Early Antigen (D): 28kd antigen of EA-D. It is used as a marker of chronic or acute infection, in EIA applications, capture assays or in western blot analysis.

RF0419 in phosphate buffered saline  

$1,750/mg 

Epstein Barr Virus, VCA P-18 & P-18/GP125 Fusion

VCA P-18 & P-18/GP125 Fusion: An important part of the VCA complex. It is a useful marker in acute and convalescent serologies. It can be used in EIA, capture assays, direct conjugation, or in western blot analysis.

RF0407* EBV VCA P-18 truncated, in phosphate buffered saline   

$1,750/mg

RF0415 VCA P-18/truncated GP125 fusion protein, in phosphate buffered saline, 3M Urea  

$1,750/mg

*Constructed as a fusion protein to truncated MBP.

Herpes Simplex Type-Specific Antigen

HSV 1 and 2 are the cause of vesicular lesions of oral and genital mucosa and may involve other sites. The use of type-specific antigens can be used to serotype individuals. 

Herpes Simplex Virus Type 1 

RF0182 Type-specific antigen gG1, in phosphate buffered saline

Autoimmune Antigen

SS-A 60 and 52 are heterogeneous antigens that are important markers in Sjogren’s Syndrome and other connective tissue diseases. JO-1 is a key marker in polymyositis and dermatomyositis as well as other autoimmune diseases. SS-B is also a significant marker in Sjogren’s Syndrome and may be seen in SLE patients. SCL-70 is a crucial marker in scleroderma and crest patients. U1-RNP is an important marker of mixed connective tissue disease.
