FC - Quality tested
IF - Reported in the literature

Application Notes:

Additional reported applications (for the relevant formats) include: immunohistochemical staining of paraffin-embedded tissue sections3-6, Western blotting2, immunoprecipitation1,2, immunofluorescence7,8, and ELISA9.

Clone M3/38 has been reported to recognize residues 48-100 in the amino-terminal domain of galectin-3.7

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.5 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 488 has a maximum emission of 519 nm when it is excited at 488 nm.
