+Tryptophan detection in the crayfish brain
Anti-Tryptophan antibody demonstrates the presence of Tryptophan positive cells in the brain of a crayfish. Staining was obtained with mouse monoclonal anti-Tryptophan antibody (IS011) and performed with STAINperfect immunostaining kit A, following the protocol for whole mount samples. Fluorescent conjugated secondary antibody was used and images obtained by confocal imaging at high magnification (x40).
DatasheetMSDS
The anti-Tryptophan antibody IS011 is a mouse monoclonal antibody optimized to ensure high affinity and specificity. Combined with the STAINperfect immunostaining kit A, this antibody allows direct L-Tryptophan visualization in whole mounts, cell cultures, and tissue sections.
