Check if the same lab product or an alternative is used in the 5 most similar protocols
Ex vivo-isolated DCs were cultured in serum-free media for 60 h. Cell-free supernatants were assayed for TGF-β by ELISA using the mouse TGF-β1 DuoSet ELISA (R & D systems). For autocrine induction of TGF-β, ex vivo-isolated DCs were stimulated with or without TGF-β (0.5 ng/mL) in serum-free media for 12 h, extensively washed, and cultured for another 48 h. Cell-free supernatants were assayed for TGF-β by ELISA.

TGFβ-1 concentration in supernatant from 4day ILC1 co-cultures and SIO-only controls was measured using the Mouse TGFβ-1 DuoSet ELISA (R&D Systems) with modified manufacturer’s instructions, whereby 100µl supernatant was incubated with the capture antibody overnight on a shaker at 4°C, not for 2h at RT. Optical density was measured in a plate reader (BioRAD) at 450nm, with correction at 540nm. Concentrations were obtained based on a regression equation (multimember regression, order 3) from the standard curve values (calculated in Microsoft Excel, version 16.16.20).
Cytometric Bead Array for Th1/Th2/Th17 cytokines was obtained from BD biosciences and performed on 10µl supernatant after 4day co-culture following the manufacturers’ instructions, using a BD Fortessa2, and analyzed following the manufacturers’ template based on a standard curve for each cytokine.

The analysis of cytokine expression in tumors of the treatment groups at the protein level was done using different ELISA kits. Mouse Th1/Th2 Uncoated ELISA (Invitrogen) was used to determine the protein levels of IFN-γ, IL-2 and IL-4. IL-1α, IL-12, TGF-β, PDGF-BB, VEGF and COX-2 were measured with the Mouse IL-1 alpha/IL-1F1 DuoSet ELISA, Mouse IL-12 p70 DuoSet ELISA, Mouse TGF-β1 DuoSet ELISA, Mouse/Rat PDGF-BB DuoSet ELISA, Mouse VEGF DuoSet ELISA and Human/Mouse Total COX-2 DuoSet IC ELISA, respectively (all from R&D Systems). TARC was determined with the Mouse CCL17/TARC Quantikine ELISA Kit (R&D Systems). For protein extraction, various sections (of 50 μm thickness) from each tumor were collected and protein lysates were prepared using RIPA buffer (20 mM Tris–HCl (pH 7.2), 150 mM NaCl, 2% (w/v) NP-40, 0.1% (w/v) SDS, 0.5% (w/v) sodium deoxycholate) and cOmplete™ Protease Inhibitor Cocktail (Sigma-Aldrich) [28] (link). The total protein concentration of each tumor sample was determined using the DC protein assay (Bio-Rad Laboratories GmbH). Equal amounts of total protein (50 μg) were diluted with ELISA-Buffer (ELISA/ELISPOT Diluent, Invitrogen), or Reagent Diluent Concentrate 2 (R&D Systems), respectively. Cytokine amounts were determined according to the manufacturers' instructions.

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.
