Caspase glo 3 7 assay kit

Manufactured by Promega
Sourced in United States, United Kingdom, Germany, France

The Caspase-Glo 3/7 assay kit is a luminescent-based assay that measures the activity of caspase-3 and caspase-7 enzymes. The kit uses a proluminescent caspase-3/7 substrate, which can be cleaved by these enzymes, resulting in the release of a signal that is proportional to the amount of caspase activity present in the sample.

Mycoplasma tested human umbilical vein endothelial cells (HUVECs; Commercially obtained from Lonza #CC‐2935) were cultured in EBM‐2 Basal Media (#00190860, #cc‐4176, Lonza, mycoplasma free) with EGM‐2 Single Quots supplements (Lonza #cc‐4176) on 0.2% gelatin (Sigma Aldrich #G1393)‐coated 96‐well plates (5,000 cells/well) or 6‐well plates (150,000 cells/well). After obtaining stable culture conditions, HUVECs were incubated with culture supernatants collected from three groups of mouse myofibroblasts: (i) untreated myofibroblasts (TurboFect), (ii) control siRNA‐treated myofibroblasts, and (iii) myofibroblasts treated with siRNA against PDGF‐Rα. For caspase activity assay, incubation with 40 μg/ml anti‐VEGF (C‐1) antibody (#sc‐7269, Santa Cruz) served as a positive control. Caspase activity was assessed after 6 h using the Caspase‐Glo 3/7 assay kit (#G8091, Promega). After 6 h of incubation, caspase activity was assessed using the Caspase‐Glo 3/7 assay kit (Promega GmbH, Germany #G8091) according to the manufacturer's instructions. Cells plated in 6‐well plate were lysed after 6‐h incubation, and lysate was processed for immunoblot analysis with cleaved caspase‐9 (Cell Signaling Technologies #9509) and eNOS (Cell Signaling Technologies #880) protein.

Caspase 3/7 activity in CLL cells was detected using the Promega Caspase-Glo 3/7 assay kit (Promega). Briefly, cells infected with shctrl or shKIAA0101 lentiviruses were plated into 96-well plates and incubated for 5 days. Next, cells were collected and cell suspensions (1×104 cells/well) were reacted with 100 μL of Caspase-Glo reaction solution. After shaking for 30 min at 300–500 rpm, the reaction system was incubated for 2 h at room temperature. Finally, signal intensity was determined using a microplate reader.

Detecting Adipocyte Apoptosis by Multiple Assays

Check if the same lab product or an alternative is used in the 5 most similar protocols
Apoptosis in adipocytes was observed and detected by various methods, including caspase 3/7 activation analysis, TUNEL assay, and flow cytometry. Caspase 3/7 activity was quantitated by using a Caspase-Glo® 3/7 Assay Kit (Promega, CA, USA) according to the manufacturer's instructions. A DeadEnd™ Fluorometric TUNEL System (Promega) was used to observe and measure the adipocyte apoptosis. The number of apoptotic adipocytes was quantitated by flow cytometry assay (Gallios, Beckman Coulter, USA) with the Annexin V/PI double-staining method according to the manufacturer's instructions. (The Annexin V/PI apoptosis assay kit was purchased from Life Technologies, USA).

The enzymatic activity of caspase-3/7 was determined using the Caspase-Glo 3/7 assay kit following the manufacturer’s instructions (Promega, Madison, WI, United States), as previously reported (Konno et al., 2014 (link)). Briefly, 3 × 103 cells were plated in triplicates in 96-well plates and transfected as indicated. An equal amount of Caspase-Glo 3/7 substrate was added to the culture and subsequently incubated for 3 h. Following incubation, caspase-3/7 activities were evaluated as an indicator of cell apoptosis using a GloMax-96 Microplate luminometer (Promega). The results were shown as the fold change relative to the control cells.

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.
