GB SARS-CoV-2 Ab

PRODUCT DESCRIPTION

This product is a semi-quantitative ELISA reagent designed for detection of IgG and IgM antibodies to SARS-CoV-2 Spike or N protein in human serum or plasma. It uses a direct sandwich ELISA format on a 96-well plate. The test requires only 10 µL of sample and has a 105-minute incubation time with a 450 nm readout. Clinical validation shows 100% sensitivity and 100% specificity. Non-Reactive results indicate no detectable anti-SARS-CoV-2 antibodies; Reactive results signify presence of antibodies, to be interpreted alongside vaccination or infection history.

GB SARS-CoV-2 Real-Time RT-PCR Multiplex Kit (E / N / ORF1ab)

PRODUCT DESCRIPTION

The GB SARS-CoV-2 Real-Time RT-PCR Multiplex Kit (E/N/ORF1ab) is an in vitro diagnostic nucleic acid amplification reagent designed for the qualitative detection of SARS-CoV-2 RNA in nasopharyngeal swab specimens.

<br>

<br>

Primers and probes simultaneously target the E gene, N gene, and ORF1ab gene of SARS-CoV-2, while an integrated RNase P extraction control (EC) monitors nucleic acid recovery and amplification integrity throughout the workflow. This ensures reliable results and minimizes false negatives caused by extraction or inhibition issues.

<br>

<br>

The assay achieves a limit of detection (LoD) of approximately 1000 copies/mL, with sample processing time suitable for <br>

<br>high-throughput laboratory workflows. Reagents should be stored at 2–8°C, protected from light, and must not be frozen.

The kit is validated across multiple PCR platforms, including the GB AIO System, Applied Biosystems QuantStudio™ 5, Bio-Rad CFX96, Qiagen Rotor-Gene Q MDx, and Roche PCR instruments, giving laboratories platform flexibility without vendor lock-in.

GB HIV Ag-Ab COMB

PRODUCT DESCRIPTION

This product is based on the ELISA sandwich principle, utilizing highly specific antigen–antibody combinations to simultaneously detect HIV-1/2 antibodies and the HIV-1 p24 antigen. In the 96-well microplate, antibodies and antigens are immobilized as the solid phase, while purified peroxidase-conjugated components serve as the detection phase. This design minimizes cross-reactivity and reduces false positives, ensuring high sensitivity and reliability.

GB HIV Ag-Ab COMB assay is a manual 4th generation solid phase Enzyme-Linked Immunosorbent assay using a mixture of antigens and antibodies for the qualitative in vitro diagnostic screening in human serum or plasma (EDTA, Heparin, and Citrate) of antibodies to HIV-1 (group M and O), HIV-2 and HIV-1 p24 antigen. The device is for professional use only.

GB HIV Ag-Ab COMB assay is intended to be used as a screening test for donated blood to prevent transmission of HIV-1/HIV-2 to recipients of blood and blood components.

GB HIV Ag-Ab COMB assay is not intended to screen and diagnose acute or primary HIV infection.

GB HIV Ag-Ab COMB assay result does not distinguish between the detection of HIV-1 antibody, HIV-2 antibody, or HIV-1 p24 antigen and is not for diagnostic use.
