T Cell based In Vivo Skin Test Assay Service
Creative Biolabs' T Cell-based in vivo skin test assay is a powerful tool designed to provide a clear go/no-go decision point early in your development pipeline. By moving beyond simple molecular binding data, we provide a direct and quantifiable measure of your therapeutic's impact on a T cell-mediated immune response. This insight is essential for validating drug candidates, confirming the immunogenicity of vaccine antigens, and streamlining your entire research program.

Introduction of In Vivo Skin Test
The skin test method is used to measure the antigen-specific T cell response using delayed-type hypersensitivity (DTH). In this test, the antigens are injected into the skin to induce a cellular response. A representative skin response is deciphered by an "induration" around the injection site, resulting from responsive memory T cell metastasis and the function of secreting cytokines at the injection site. The diameter of the "induration" reflects the collective production of cytokines that can describe the whole response of immune cells. The method has many merits over other available approaches.

Powerful In Vivo Validation
Using Creative Biolabs' assay in our research has significantly improved our ability to confirm the functional efficacy of our lead candidates. We've seen a clear correlation between the assay's DTH read-outs and later preclinical data. - Eri**. -
Streamlined Translational Research
Our team needed a bridge between our in silico prediction models and our in vivo efficacy studies. The T Cell-based in vivo skin test assay provides that link seamlessly and is a highly professional and reliable service. - Jon**.
FAQs
How does the assay differ from standard in vitro methods?
While in vitro assays are excellent for initial screening, our in vivo assay provides a crucial advantage by measuring T-cell function within the complex, physiologically relevant context of a living organism. It accounts for the intricate cellular interactions and microenvironment signals that are often missing in a petri dish, providing more predictive and translatable data.
Is your assay applicable to my specific disease indication?
Yes. The underlying principle of the assay-measuring--T cell-mediated DTH--is fundamental to a wide range of diseases. We have successfully applied this assay in projects related to infectious diseases, autoimmune disorders, and immuno-oncology.
