Cytokine Analysis of Lentiviral Vaccine Therapy

Check if the same lab product or an alternative is used in the 5 most similar protocols
Blood (centrifuged at 3000 g for 30 min at room temperature) and tumor homogenates (150 mg tumor tissue) were harvested from Lenti-AFP-, Lenti-HA-treated or control HCC mice and followed by analysis of IFN-γ (R&D systems, US), IL-2 (eBioscience, US), IL-10 (MultiSciences Biotech Co., Ltd., China) and TGF-β kits (MultiSciences Biotech Co., Ltd., China), respectively. To examine the immune response in orthtopic HCC mice treated with repeated administrations of lentiviral vaccines in a real-time manner, we collected blood 3 days after each injection via retro-orbital bleeding. For murine in vitro study, IFN-γ and IL-2 ELISA kits were purchased from R&D systems and eBioscience (US). For human in vitro cytokine assay, IFN-γ and IL-2 ELISA kits were purchased from Dakewe Biotech Co., Ltd (China). Briefly, 1x105 activated BMDCs (transduced with lentivirus), inguinal lymph node CD11c+DC or peripheral monocyte-derived DCs (PMDCs) were incubated with 1x106 mixed splenocytes from naïve mice or human lymphocytes for 72 hrs. Levels of IFN-γ and IL-2 in supernatant were detected as per the manufacturer's instructions.

Protein samples were prepared using the extraction buffer supplemented with a protease inhibitor PMSF as mentioned above. Homogenate was centrifuged at 12,000 rpm for 15 min at 4 °C, and the supernatant was collected for TNF-α, IL-1β, IL-6, IL-4, IL-10 (MULTI SCIENCES), and thrombin (Elabscience) ELISA assay. The contents of the cytokines were expressed as pg/ml/105 cells for the supernatant, and pg/mg for the lysate of the cells and the cord tissues. Plates were read with a multifunctional enzyme marker (Biotek Synergy2) at a 450-nm wavelength.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
