Being able to phenotype a cell population is fundamental to understanding the characteristics and capabilities of a cell. Utilize our plethora of resources below to learn more about your cells, plan out experiments, and make breakthroughs.

CD Markers

The HLDA Workshops characterize leucocyte surface molecules. They organize monoclonal antibodies against leukocyte markers into "clusters of differentiation" (CD) that target the same molecules. With over 400 CD molecules designated, our webpage helps you these molecules to find the right reagents.

Chemokines and Receptors

Chemokines are a class of cytokines that induce chemotaxis (migration) of target cells. While some chemotaxis is induced by inflammation or damaged cells, other chemokines function in homeostasis. Browse through our antibodies and recombinant proteins for chemokines and their respective receptors.

Interleukin Receptors

Interleukin cytokines interact with receptors on cells to execute a variety of functions like inflammation, proliferation, and suppression. Learn more about these receptors with our helpful webpage.

Integrin Explorer

Integrins are mainly known for mediating cell and extracellular matrix adhesion and migration. They are integral in cell growth, division, differentiation, and apoptosis. But, they also play a role in broader biological events, like wound healing and apoptosis.

Toll-Like Receptors

TLRs are heavily involved in innate immunity and are expressed on a variety of cell types. These pattern recognition receptors help detect bacteria, fungi, protozoa, and viruses. TLR activation leads to a wide range of effects, including inflammation, complement activation, and phagocytosis.

Transcription Factors

Transcription factors are proteins that regulate the transcription of genes, or the production of mRNA from DNA. It is the action of transcription factors that determines the differentiation fate of cells. Learn about these factors and how they influence the development of cell subclasses.
