Find and select primary antibodies for participating proteins of key cell signaling pathways: extracellular growth factors, membrane receptors, GTPases, protein kinases, response elements, binding proteins, and transcription factors. Well known signaling pathways and related classes of proteins include the MAPK/ERK pathway, AKT pathway, Wnt pathway, phosphoproteins (serine- or tyrosine-phosphorylated proteins), and transcription factors.

Featured categories of cell signaling pathway primary antibodies

AKT Signaling Pathway Antibodies

Connect to antibodies specific for AKT, also known as protein kinase B (PKB), and members of its pathway, including AKT1, AKT2, AKT3, PI3K, 4E-BP1, FGF-Basic, FGFR1, FOXO3, GSK-3β, and GSK-3α.

GTPase Antibodies

Discover antibodies to GTPases and members of its sub families, such as the RAS super family which is critical to cell signaling: RAC, RAS, ARF, RHO, RAB, and Cdc42.

MAPK Signaling Pathway Antibodies

Learn about and find antibodies to mitogen-activated protein kinases (MAPK), including MAP2K, MAP3K, ERK1/2, JNK1/2 and p38-alpha (MAPK14) members of this protein kinase cascade.

Phosphospecific Antibodies

Select from more than 300 phosphorylation site-specific antibodies (phospho-specific antibodies) to enable analysis of key targets in normal and disease states.

Transcription-Specific Antibodies

Find antibodies to key transcription factors, which are proteins that bind to specific DNA sequences and regulate the transcription of mRNA from DNA by activating or inhibiting RNA polymerase.
