Ein kompetitiver ELISA misst Analytkonzentrationen über ein invertiertes Signal: Probeantigen und ein markierter Tracer konkurrieren um dieselben, begrenzten Bindungsstellen. Je mehr Analyt in der

An antibody–drug conjugate is not a targeted drug. It is a delivery problem with an antibody bolted to the front of it. Binding is the easy part, and it is almost never the part that fails. What deci

Introduction Tumorigenesis, the process by which normal cells transform into cancer cells, is a multifaceted and complex event influenced by various internal and external factors. Among the

CD155 is read by four different receptors, and only one of them turns the killing programme on. The nectin and nectin-like ligands induced on stressed and transformed cells are simultaneously an acti

What You Need to Know About TocilizumabWhat is Tocilizumab?Tocilizumab is a monoclonal antibody that targets the interleukin-6 (IL-6) receptor, widely used for managing autoimmune and in

By Rachel Bleach, PhD Student, RCSI By the age of 79 years, 1 in 14 women will develop breast cancer (Global Burden of Disease Cancer 2017). Beatson reported

Written by Seán Mac Fhearraigh, PhD  •  Updated: 19 May 2026  •  ~9 min read Quick Answer The five main types of ELISA are sandwich, competitive, direct, indirect and multiplex. Sandwich ELISA is

Platelet activation plays a pivotal role in hemostasis, the process that stops bleeding and initiates wound healing. Central to this process is the activation of G protein-coupled receptors (GPCRs

Interleukin signaling is involved in a number of biological processes, including cell growth and differentiation, inflammation and immunity. Interleukins are glycoproteins which act on hema

Quick answer A competitive ELISA is running correctly when the blank (zero standard) gives the highest OD, the standard curve drops smoothly with rising concentration, and your samples land in the

Cell Signalling Cell signalling pathways have an important role in integrating a plethora of extracellular and intracellular signals to produce a controlled optimal o

Low-dose IL-2 expands regulatory T cells. High-dose IL-2 expands the cells they exist to restrain. Same cytokine, same receptor family, opposite clinical intent — and the explanation is a receptor su

Cell Signalling · MetabolismInsulin Signalling & Receptor Tyrosine KinasesInsulin controls metabolism and growth through the insulin receptor — a receptor tyrosine kinase that branches into the

Chemokines are small signaling proteins that play a crucial role in the immune system by directing the movement of cells, orchestrating immune responses, and maintaining tissue homeostasis. The

Cell Signalling · CytokinesJAK-STAT Signalling: Mechanism, Regulation and InhibitorsJAK-STAT is the shortest route from a cytokine outside the cell to a change in gene transcription — receptor engagem

An agonist antibody does not activate its receptor. It gets held still by something else, and the receptors underneath cluster because they are crowded. That sentence sounds like a technicality and i

Almost all of the TGF-β in a tissue is already there, and almost none of it is active. That single fact reorganises how the pathway should be studied. Unlike most cytokines, TGF-β is deposited into t

Phagocytosis is a subtraction, not a switch. A macrophage engulfs when its activating signals exceed its inhibitory ones, and every awkward result in the myeloid checkpoint field falls out of that on
