Rapid-Lenti HIV-1 p24 ELISA Kit (Single Wash)

2BScientific are excited to present XpressBio's Rapid Kit, designed to expedite your HIV-1 p24 testing process while maintaining accurate results.

  • Faster Assay Time
    The Rapid Kit reduces assay time to approximately 90 minutes, compared to around 3 hours with the Regular Kit. Get critical information quicker and make timely decisions.
  • Streamlined Process
    The Rapid Kit minimises procedural steps, including the number of washes and incubations, for a more efficient testing experience.
  • High Sensitivity
    The Rapid Kit maintains sensitivity levels of 3-200pg/ml or 4.7-300pg/ml, ensuring accurate detection without compromising quality.
  • Reliable Reproducibility
    With an R2 value of 0.9977 (for 200pg/ml) or 0.9772 (for 300pg/ml), the Rapid Kit delivers high reproducibility and precision.
  • Ideal for High Throughput Screening
    The Rapid Kit is perfect for quickly determining HIV-1 p24 levels in large sample sets, saving you time and resources.

HIV Virus

Virologists, immunologists, and molecular biologists engaged in the study of HIV-1 and its pathogenesis can benefit from the Rapid Kit.

By utilising this kit, researchers can efficiently analyse p24 antigen levels in experimental samples, enabling them to investigate viral replication, immune responses, and potential therapeutic interventions.

The Rapid Kit provides researchers with a valuable tool to advance their understanding of HIV-1 and contribute to the development of effective strategies for diagnosis, treatment, and prevention.

Absorbance vs Cas9 Concentration

  • Streamlined Processes
    Easy-to-follow protocol that simplifies implementation.
  • Flexible and Convenient
    ELISA strips used in the assay are removable, enhancing convenience and flexibility.
  • Highly Sensitive
    The Cas9 ELISA assay is highly sensitive, capable of detecting as little as 1.1 ng/ml of Cas9, making it suitable for detecting low concentrations of theprotein.

Cas9 ELISA Assay

Another new product 2BScientific proudly presents from XpressBio is the Cas9 ELISA Assay.

The Cas9 ELISA assay is a valuable tool with multiple applications. It enables the screening of Cas9 protein levels in cell culture, allowing researchers to assess its presence and abundance.

The assay also facilitates the quantitation of Cas9 using an ELISA platform, providing a precise measurement of the protein's concentration. This is particularly useful for monitoring the efficiency of gene editing systems, as it allows scientists to track changes in Cas9 levels over time.
