Donkey anti-Goat IgG (H&L), DyLight® 488 conjugated

Purified Goat IgG, whole molecule

Immunofluorescent localization of V-ATPase epsilon subunit of tonoplast H+ATPase in suspension culture of Oryza sativa ssp. japonica cv. 'Unggi 9', using goat anti-V-ATPase, epsilon subunit of tonoplast antibodies (AS09 577A) and donkey anti-Goat IgG (H&L), DyLight® 488 conjugated secondary antibodies (AS10 1116, Agrisera).  Vacuolar membrane, tonoplast, is highlighted by yellow arrowheads. DAPI staining of nuclei is pseudocolored red.

Conjugate is present in 10 mM Sodium Phosphate, 0.15 M Sodium Chloride, pH 7.2, 1 % (w/v) BSA, Protease/IgG free. 0.05 % (w/v) sodium azide is added as preservative.

No reactivity is observed to, non-immunoglobulin goat serum proteins

BSA and milk have to be replaced by other blocking reagents, like doneky serum or commercial formulations which are free from bovine IgG.

Donkey anti-Goat IgG (H&L), DyLight®488 Conjugated is a secondary antibody conjugated to DyLight® 488, which binds to Goat IgG (H&L) in immunological assays.

DyLight® 488 has Amax = 493 nm, Emax = 518 nm. Antibodies are purified using solid phase Goat IgG (H&L)
