Target Background
Transforming growth factor β1 (TGFB1) is a cytokine that has an important role in a number of different cellular functions, such as, proliferation, differentiation, chemotaxis, apoptosis and tumor suppression. It plays a crucial role in bone metabolism where is acts as a coupling factor between bone resorption and bone formation. TGFB1 has affinity to TGFB1, 2 and 3 receptors. Downstream TGFB1 signaling activates Smad proteins, mitogen-activated protein kinases and protein kinase B. Mutations in the gene can result in Camurati-Engelmann disease (characterized by increased bone density). Numerous cancer cells are also known to secrete increased levels of TGFB1.

Customize This Human TGF-beta 1 ELISA
We manufacture our ELISAs in-house, so we can build a custom version for your study.
- Post-translational modifications (PTMs): Detect modified TGF beta 1 (TGFB1), including phosphorylation, acetylation, S-nitrosylation, S-acylation, oxidation, lactylation, sumoylation, ubiquitination, nitration, carbamylation, and more
- Sample types: Validation in your matrix using samples you provide, such as CSF, urine, saliva, lysates, or exosomes
- Also available: More sensitive platforms such as Simoa® and NexaTag®, multiplex panels, bulk lots, and other species when suitable reagents exist
Feasibility varies by target and modification, and we’ll tell you upfront what’s achievable.
