The MycoGenie Rapid Mycoplasma Detection Kit enables the detection of 28 Mycoplasma species in under 1 hour using a simple visual determination method, eliminating the need for expensive

In the periphery, co-stimulation rescues a T cell. In the thymus, the same molecules kill it. A peripheral T cell that engages its receptor without CD80 and CD86 becomes anergic; engage them and it r

Not one immune cytokine on this pathway touches bone. TNF, IL-1β, IL-6 and IL-17A all act on osteoblasts, osteocytes and synovial fibroblasts, and it is those stromal cells that decide between RANKL

Double-stranded DNA in the cytosol is always a mistake. A virus has uncoated, a mitochondrion has ruptured, a micronucleus has burst, or a chromosome has been broken and left unrepaired. cGAS treats

Introduction Transformation of bacteria with plasmids is not only of note for bacterial studies but also can be used for gene expression studies in mammalian cells. Most plasmids are of bact

Soporte técnico ELISA: qué comprobar antes de llamar Si su ensayo ELISA falla, haga estas tres comprobaciones inmediatas: controles, equipo y reactivos, en ese orden. Antes de contactar con soporte t

Most immunology is written as though a T cell must first be told what to look for. Three lineages did not read that memo. γδ T cells, invariant NKT cells and MAIT cells leave the thymus with their ef

Tocilizumab reverses cytokine release syndrome within hours, and it never touches the cell that started it. That sentence contains the whole mechanism. The trigger is a T cell — engaged by a CAR, a b

Over the past few years I have traversed through academia in a few different guises, first as a PhD student for about 5 years, then onto the traditional route of a post-doc, followed by a sales

Cell counting is an important part of many different scientific experiments, enabling researchers to gather crucial data about cell populations and their characteristics. In this step-by-st

The Spanish flu pandemic of 1918-1919 was the deadliest in history. It is estimated that up to 100 million people died from the virus, which is more than three times the number who d

What is Xeroderma Pigmentosum? Xeroderma pigmentosum (XP) also known De Sanctis-Cacchione syndrome is a rare genetic disorder that affects the skin, eyes and central nervous system. It is ca

Valider en labo vos anticorps pour western blot : testez 2–3 dilutions Pour un Western blot fiable, choisissez un anticorps validé sur des lysats biologiques pertinents, plutôt qu’un anticorps choisi

Problemas ELISA: guía práctica para diagnosticar y corregir fallos Ante un resultado inesperado, lo primero es revisar los controles: blanco, negativo, positivo y curva estándar. Si la curva es plana

Almost any inflammatory phenotype in a mouse can be assigned to a cytokine by taking that cytokine away. Neutralisation is the most direct causal test immunology has: inject a functional-grade antibo

The antigen tells a CD4 T cell to respond; the cytokine tells it what kind of response to make. A naive CD4⁺ T cell leaving the thymus is uncommitted. Within about seventy-two hours of engaging TCR/C
