TFAmber-NP

Non-permeant yellow fluorogen for selective labeling of cell-surface FAST proteins.

TFAmber-NP (HBRAA-3E) is a membrane-impermeant yellow fluorogen that stays outside the cell, so it selectively labels FAST-tagged proteins at the cell surface — ideal for trafficking and internalization studies.

Key properties

  • Fluorogen for: FAST1, pFAST
  • Excitation / Emission: ~505 / ~559 nm (yellow)
  • Cell-permeant: no (non-permeant)
  • Format: 250 nmol per tube (1 EA)
  • Reference (SKU): 505559-250

Applications

Selective cell-surface labeling, membrane-protein trafficking and internalization assays, and pulse-chase experiments.
