Product nameDonkey Anti-Goat IgG H&L (Alexa Fluor® 405) preadsorbed
See all IgG secondary antibodies
SpecificityBy immunoelectrophoresis and ELISA this antibody reacts specifically with goat IgG and with light chains common to other goat immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins. Less than 1% cross reactivity to chicken, human, mouse, pig, rabbit and rat IgG was detected. This antibody may cross react with IgG from other species.
Tested applicationsSuitable for: IHC-Fr, ICC/IF, ELISA, IHC-P, Flow Cytmore details
Chicken, Human, Mouse, Pig, Rabbit, RatTo ensure minimal cross-reactivity, the antibody has been pre-adsorbed with serum proteins from the following species.more details

Our Abpromise guarantee covers the use of ab175665 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-Fr||Use at an assay dependent concentration.|
|ICC/IF||1/200 - 1/1000.
We recommend the use of a dedicated 405 filter for optimal results not the DAPI filter. The DAPI filter may not excite until the maximum emission peaks of Alexa Fluor® 405 dye (see difference below)
|ELISA||Use at an assay dependent concentration.|
|IHC-P||Use at an assay dependent concentration.|
ICC/IF image of ab7291 stained HeLa cells. The cells were 100% methanol fixed (5 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then incubated in 1%BSA / 0.3M glycine in 0.1% PBS-Tween for 1h to block non-specific protein-protein interactions. The cells were then incubated with the primary antibody (ab7291, 1µg/ml) overnight at +4°C. Ab98800, goat anti-mouse IgG, was then added as a secondary bridging antibody, at 1/250 dilution for 1h. Ab175665 Alexa Fluor® 405 Donkey polyclonal Secondary Antibody to Goat IgG - H&L pre-adsorbed (blue) was then used at 1µg/ml for 1h as a tertiary antibody. DRAQ5™ (ab108410) was used to stain the cell nuclei (red) at a concentration of 1.25µM.
The negative control (inset) is a secondary-only assay to demonstrate low non-specific binding of the secondary antibody.
Postnatal day 6 mouse testes were fixed with 4% paraformaldehyde. Tissue was embedded in O.C.T. and frozen. 5 micron sections were cut and transferred to slides. Sections were permeabilized with 0.1% Triton X-100 in PBS, and blocked with 3% BSA in 0.1% Triton X-100 + PBS. Sections were incubated with either (A) no primary antibody or (B) Goat Anti-DDX4 at a 1/800 dilution for 1 h at RT. Sections were then washed 3X with 0.1% Triton X-100 in PBS and Donkey Anti-Goat IgG H&L (Alexa Fluor® 405) (ab175665) applied at a 1/500 dilution. Sections were then mounted after washing 3X with 0.1% Triton X-100 in PBS.
