AOPP-HSA Modulates RA-FLS Inflammatory Response

Check if the same lab product or an alternative is used in the 5 most similar protocols
RA-FLSs were stimulated with the indicated concentration of AOPP-HSA (50, 100, or 200 µg/ml) for 48 hours or treated with 100 µg/ml AOPP-HSA for the indicated time (6, 12, 24, or 48 hours). Then, cell supernatants were collected and centrifuged at 12,000 g for 15 minutes. Supernatants were stored at -80°C until use. The levels of IL-6, TNFα (Boster, China), MMP-3, and MMP-13 (R&D Systems, USA) in the supernatant were quantified using enzyme-linked immunoabsorbent assay (ELISA) kits according to the manufacturer’s protocol. The optical density (OD) was measured at 450 nm with a spectrophotometric plate reader.
In a blocking test, RA-FLSs were pretreated with or without a neutralizing anti-RAGE antibody (10 µg/ml) for one hour, followed by treatment with AOPP-HSA (100 µg/ml) for 48 hours. The levels of IL-6, TNFα, MMP-3, and MMP-13 were detected. All experiments were performed in triplicate.

Enzyme-Linked Immunosorbent Assay for MMP-10 Antibodies

Check if the same lab product or an alternative is used in the 5 most similar protocols
Recombinant human MMP-10 (R&D Systems) was diluted (0.1 μg/ml) in carbonate coating buffer, added to Immulon 1B ELISA plates (Thermo Scientific), and incubated overnight at 4 °C. All remaining incubations were conducted on a platform shaker set at 200 revolutions per minute at room temperature. The plates were incubated with a 3% bovine serum albumin (BSA; Equitech-Bio, Inc.) in PBS–0.05% Tween 20 (PBST) blocking buffer. Plates were incubated with patient serum or joint fluid samples (1:200) or the positive control anti-MMP-10 MAb910 (1:200; R&D Systems). Following washes with PBST, horseradish peroxidase–conjugated goat anti-human IgG (Santa Cruz Biotechnology) or horseradish peroxidase–conjugated donkey anti-mouse IgG (Santa Cruz Biotechnology) was added, followed by TMB substrate (BD Biosciences). For interplate standardization, the positive control MAb910 was included on each plate. A positive antibody response was defined as >3 SD above the mean in 58 healthy subjects; this mean + 3 SD value characteristically corresponded to >0.51 OD450.
To examine specificity of the antibody response to MMP-10, serum samples were also tested with MMP-3 (R&D Systems), using the same methods detailed for MMP-10. Seropositivity responses to the B. burgdorferi were analyzed by ELISA and Western blot as previously described [49 (link)–51 (link)].

Serum Biomarker Profiling Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Serum samples were obtained preoperatively or before white light cystoscopy. Venous blood (10 ml) was collected and centrifuged at 900 rpm for 10 minutes. The serum was then separated, aliquoted in 2 ml fractions and stored at −80°C until further use. Protein serum levels were assessed by the multiplexed particle-based flow cytometric cytokine assay (Vignali, 2000). Kits for VEGF-A, VEGF-C and VEGF-D were purchased from Millipore (Zug, Switzerland), for MMP-2, MMP-3 and MMP-7 from R&D Systems (Oxon, UK) and for VEGF-R2 and VEGF-R3 from eBioscience (Vienna, Austria). The procedures closely followed the manufacturer’s instructions. The analysis was conducted using a conventional flow cytometer (Guava EasyCyte Plus, Millipore, Zug, Switzerland) [22 (link)].

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.
