LDV FITC

Fluorescent ligand that binds to theα4β1integrin (VLA-4) with high affinity (Kdvalues are 0.3 nM and 12 nM for binding to U937 cells in the presence and absence of Mn2+respectively). Used to detect VLA-4 affinity and conformational changes.

LDV-FITC, a fluorescent peptide, is a FITC-conjugated LDV peptide (HY-P2267). LDV-FITC binds to the α4β1 integrin with high affinity (Kd: 0.3 nM and 12 nM for binding to U937 cells in the presence and absence of Mn2+ respectively). LDV-FITC can be used to detect α4β1 integrin affinity[1][2].
