What we offer:
We offer precise measurement of cell cycle phases (G0/G1, S, and G2/M) and proliferation rates using DNA content analysis and EdU incorporation assays.
Applications include:
- Cancer research to study tumor cell proliferation and cell cycle regulation.
- Drug development to assess anti-proliferative effects of therapeutic candidates.
- Toxicology studies to evaluate cytotoxicity and genotoxicity.
Why choose our service?
Our advanced flow cytometer provides accurate cell cycle discrimination, helping researchers to identify cell cycle dysregulation and evaluate drug efficacy.
4. Apoptosis and Viability Assays
When is it needed?
Apoptosis and viability assays are essential for assessing cell death mechanisms and cytotoxic effects. These assays are widely used in cancer research, drug development, and immunology studies.
What we offer:
We provide quantification of apoptotic and viable cells using Annexin V, Propidium Iodide (PI), and other apoptosis markers. Our assays detect early and late apoptosis stages, ensuring comprehensive analysis of cell health and death.
Applications include:
- Evaluating drug-induced apoptosis in cancer therapy research.
- Assessing cytotoxicity of new chemical entities or biologics.
- Studying immune-mediated cell death in infectious disease and autoimmune research.
Why choose our service?
Our sensitive detection methods ensure accurate identification of apoptotic markers, providing critical data for drug safety and mechanism-of-action studies.
5. Cytokine and Intracellular Protein Detection
When is it needed?
Cytokine and intracellular protein detection is crucial for understanding cell signaling pathways, immune responses, and inflammatory processes. It is commonly used in immunology, cancer research, and infectious disease studies.
What we offer:
We measure intracellular cytokines and signaling proteins using high-sensitivity flow cytometry, allowing multi-parameter analysis of signaling events and immune cell activation.
Applications include:
- Immunology research to profile cytokine production in T cells, B cells, and macrophages.
- Cancer immunotherapy studies to assess cytokine release profiles.
- Inflammation and infection studies to evaluate immune responses.
Why choose our service?
Our platform enables simultaneous detection of multiple intracellular markers, providing comprehensive insights into signaling networks and immune responses.

Case Studies
Immune Oncology Novel Drug Target Discovery
- Challenge: What is the target of the checkpoint inhibitor Vista?
- Background: Vista is a receptor expressed on cancer cells that inhibits activated T-cells from recognizing and killing cancer cells. The LRC-TriCEPS experiment used the extracellular domain of Vista fused with an Fc-tag as the ligand to identify the target on activated T-cells from different donors. At physiological pH 7.4, no target could be identified, but at acidic pH 6.0, PSGL-1 was discovered as the target. The acidic dependency of this interaction was confirmed using different techniques. This experiment mimicked the acidic tumor environment in patients, leading to the identification of a novel drug target.
- Take-home message:
- Novel drug target PSGL-1 identified using the LRC-TriCEPS platform.
- The microenvironment is essential for receptor-ligand interactions.
- Receptor discoveries can best be studied on living cells for a more accurate reflection of patient responses.

Novel Drug Target for Asthma Treatment
- Challenge: What proteins are targeted at the cell surface by house dust mite, leading to allergic reactions?
- Background: Researchers at the University of Central Florida wanted to understand how house dust mite induces allergies that may lead to asthma. A house dust mite protein extract was used as a ligand in an LRC-TriCEPS experiment on dendritic cells, identifying LMAN1 as the target. The group confirmed that LMAN1 is downregulated in asthmatic patients and could potentially be used as a novel drug target.
- Take-home message:
- The LRC-TriCEPS platform can identify targets of complex protein or peptide mixtures on the surface of living cells.

Mode of Action of a Cytokine Inhibitor (TIMP-1)
- Challenge: What is the mode of action of the cytokine inhibitor TIMP-1?
- Background: TIMP-1 plays a role in inflammatory diseases and cancer, but its interaction with immune cells was unclear. The LRC-TriCEPS platform identified a novel target on the surface of a monocyte cell line, showing that TIMP-1 triggers monocyte activation, a key mechanism in diseases like cancer, sepsis, and acute pancreatitis.
- Take-home message:
- The LRC-TriCEPS platform identified a novel mechanism of action by revealing that TIMP-1 activates monocytes, a crucial factor in inflammatory diseases.
Link to publication: TIMP-1 is a Novel Ligand of Amyloid Precursor Protein and Triggers a flammatory Phenotype in Human Monocytes
Cardiac-Specific Peptide Targeting
- Challenge: How does a cardiac-specific peptide enter cardiac cells?
- Background: Before the LRC-TriCEPS screen, there was no hypothesis regarding the target or how the peptide entered cardiac cells. The screen revealed that a voltage-gated potassium channel was the entry point for the 12-amino acid peptide.
- Take-home message:
- The target of a peptide or protein screen may not always be a receptor; in this case, it was a channel.
