Vaccine Evaluation Reagents: Solutions for VZV Vaccines Development

Varicella zoster virus(VZV) Vaccine Evaluation Tools:

Antigens: 

• Covering Envelope Glycoprotein E (gE), gH&gL, gI&gE antigenic proteins.
• High purity verified by SDS-PAGE and high homogeneity verified by SEC-MALS.
• The binding activity of the antigen and its antibody was verified by ELISA with a linear range of 0.1-4ng/ml; 

Antibodies:

• High sensitivity and specificity, can accurately detect gE protein in samples; 
• Recombinant expression in HEK293 cells with good batch-to-batch stability; 
• Can be used for gE protein detection or as an antibody standard.

Antigen detection kits:

• High sensitivity: The sensitivity of the kit is over 39 pg/mL; 
• Wide detection range: The detection range of the kit is 39-1250pg/mL, which can meet the detection needs of different concentrations; 
• High precision: CV values of intra- and inter-assay precision are <10%

IgG titer detection kits

• High precision: CV values of intra- and inter-assay precision are <10%; 
• High recovery rate: the recovery rate is within 80%-120%; 
• Provide kits for human and mouse sample detection, supporting the evaluation of humoral immunity in preclinical and early clinical stages.

ELISpot Assay Kits:

• High sensitivity, high precision and high stability ELISpot cytokine detection kits
• Covering INF - gamma, TNF alpha, IL - 2 cytokines.
• Supporting the evaluation of cellular immunity in preclinical and early clinical stages.
