Bio plex pro human mmp panel 9 plex

Manufactured by Bio-Rad
Sourced in United Kingdom

The Bio-Plex Pro Human MMP Panel 9-plex is a multiplex assay designed to measure the levels of 9 different matrix metalloproteinases (MMPs) in biological samples. This panel allows for the simultaneous quantification of MMP-1, MMP-2, MMP-3, MMP-7, MMP-8, MMP-9, MMP-10, MMP-12, and MMP-13 using the Bio-Plex suspension array system.

Conditioned media samples with a total protein concentration of 800 μg/mL were used for the detection of secreted IL-2, IL-4, IL-6, IL-8, IL-10, GM-CSF, IFN-γ and TNF-α cytokines using a Bio-Plex Pro Human Cytokine 8-plex panel (Bio-Rad), as previously described10 (link). Secreted IL-1β was separately quantified using Bio-Plex Pro Human Cytokine Standard 27-plex, Group I, magnetic beads and detection antibodies for human IL-1β (Bio-Rad). MMP-1, -2, -3, -7, -8, -9, -10, -12 and 13 were assessed using a Bio-Plex Pro Human MMP panel 9-plex (Bio-Rad). The cytokine and MMPs levels were analysed according to the manufacturer’s instructions using a Bio-Plex MAGPIX System and Bio-Plex Manager software version 6.0 (Bio-Rad).

Supernatants of micromasses derived from control siRNA (NC) or NOTCH1 siRNA (N1) chondrocytes were used to test the role of NOTCH1 on the expression of major matrix metalloproteinases, across micromass maturation.
To this end we used the Bio-Plex Pro™ Human MMP Panel, 9-Plex (Bio-Rad Laboratories, #171AM001M), a multiplex bead based sandwich immunoassay kit, with high sensitivity and dynamic range, to simultaneously evaluate the three collagenases (collagenase1/MMP-1, collagenase 2/MMP-8 and collagenase 3/MMP-13), the two stromelysins (stromelysin1/MMP-3 and stromelysin2/2MMP-10), the two gelatinase A (72 kDa, MMP-2) and B (92 kDa, MMP-9), the matrylisin/MMP-7, and the macrophage metalloelastase MMP-12.

Multiplex Measurement of Serum Chemokines and MMPs

The levels of chemokines and cytokines were measured using Bio-Plex Pro Human Chemokine Panel 40-plex (Bio-Rad Laboratories, Hercules, CA, Cat # 171-AK99MR2). The concentrations of MMPs were measured using Bio-Plex Pro Human MMP Panel 9-plex (Bio-Rad Laboratories, Cat # 171-AM001 M). Based on expected chemokine or MMP values in serum and the known ranges for the Bio-Plex kits, serum samples were diluted for optimal detection. Samples were randomized for analysis using GraphPad Software (GraphPad Software, Inc, La Jolla, CA). For the 40-plex, 25 μl of each serum sample was diluted to 50 μl with provided serum diluent and then used for the immunoassay. For the 9-plex, 12.5 μl of each serum sample was diluted to 50 μl with the provided sample diluent HB. The manufacturer’s protocol was followed for the remainder of the protocol.

MMP and TIMP protein concentrations were measured using multiplex, bead-based (Luminex) assays on a Bio-Plex 200 suspension array system in accordance with each manufacturer’s instructions. The Bio-Plex Pro Human MMP 9-Plex Panel and Bio-Plex Pro Human TIMP 4-Plex Panel (Bio-Rad Laboratories, Watford, UK) were used for detection of MMPs and TIMPs in cell medium. Total and Phospho ERK protein concentrations were measured in cell lysates using Milliplex MAP Kit (2-Plex Total/Phospho ERK, Merck KGaA, Darmstadt, Germany). Data were acquired on a validated and calibrated Bio-Plex 200 system (Bio-Rad Laboratories, Watford, UK) and analyzed with Bio-Plex Manager 6.0 software (Bio-Rad Laboratories, Watford, UK) with a detection target of 50 beads per region, low RP1 target for CAL2 calibration, and recommended doublet discriminator (DD) gates of 5000–25,000 for Bio-Plex. The median fluorescence intensity (MFI) was measured.

Conditioned media was collected from HGSOC adhesion assays using two unique AAM donors and centrifuged at 1,000g for 15 minutes at 4°C. The supernatant was diluted 1:2 in 1% bovine serum albumin (BSA, Sigma, St. Louis, MO) in SFM and assayed by Bio-Plex Pro™ Human MMP 9-Plex Panel and Bio-Plex Pro™ Human Cytokine 27-plex Assay (Bio-Rad), using the MagPix® instrument (Luminex Corporation, Austin, TX).
Informed, written consent was obtained from patients recruited under a study approved by the Institutional Review Board at the University of Wisconsin-Madison. Studies were conducted in accordance with recognized ethical guidelines (e.g., Declaration of Helsinki, CIOMS, Belmont Report, U.S. Common Rule). Ascites was collected from patients with HGSOC (n=20) or benign conditions (n=4). Samples were diluted 1:2 in 1% BSA/PBS and assayed using a human MIP-1β DuoSet ELISA following manufacturer’s 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.
