Mechanistic Assays

Understanding the biology of a disease is critical to discovering new therapies for its management. Mechanistic assays offer a valuable tool to get a better understanding of the regulatory processes within a healthy body and to identify the relevant ‘triggers’ that lead to disease development.

At Cellomatics, our team of scientific experts can support your mechanistic assays and drug discovery programmes in several ways using 2D or 3D cell culture models:

  1. Identifying the relevant signalling pathway(s)
  2. Identifying/validating the disease biomarker of interest
  3. Understanding the molecular mechanism of action

Pathway activation: Protein Analysis

IC-21 cells were stimulated with LPS for various time points to analyse the pathway proteins. Chemiluminescence imaging of IC-21 cell lysates to investigate activation of NFκB signalling. 

Pathway activation: Gene Expression

Cell lines – A431, MCF7 and HeLa were stimulated with EGF, IGF-1 and TNFα respectively. The stimulated cell lysates along with unstimulated lysates were then investigated for multiple signalling pathway activation using Multiplex Quantigene Assay (Luminex).

Normalised absorbance values for p-AKT (A) and p-ERK (B) for 4 control conditions: untreated, VEGF-A treated, Axitinib and Wortmannin. Co-treatment with Wortmannin/VEGF-A and Axitinib/VEGF-A illustrated lower levels of p-AKT and p-ERK, indicating inhibition of the CXCR4 receptor and its signalling pathway. 

SIRT2 Activity Assay

SIRT2 Activity Assay is designed for the rapid and sensitive evaluation of SIRT2 inhibitors or activators using recombinant SIRT2 or purified SIRT2.

Applications include:

1. Screening inhibitors or activators of SIRT2.

2. Detecting the effects of pharmacological agents on SIRT2.

SIRT2 activity assay – Deacetylase activity of recombinant SIRT2 is measured by incubation with fluorescence substrate. A) Time-course of SIRT2-substrate deacetylation in the presence of SIRT2 inhibitor Sirtinol showing B) a dose-dependent decrease in SIRT2 activity, relative to the solvent control (DMSO). Data plotted as mean ± STD from triplicates, *p<0.05; **p<0.01; ***p<0.0001, using unpaired t-test between treatments and solvent control
