  • Description

    Donkey polyclonal Secondary Antibody to Goat IgG - H&L (Alexa Fluor® 488), pre-adsorbed
  • Host species

  • Target species

  • Specificity

    By 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.

ELISA Use at an assay dependent concentration.


  • ICC/IF image of ab7291 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the 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. Ab150133 Alexa Fluor® 488 donkey anti-goat IgG (H+L) (green) was then used at 2µg/ml for 1h as a tertiary antibody. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    The negative control (inset) is a secondary-only assay to demonstrate low non-specific binding of the secondary antibody.

Immunocytochemistry/ Immunofluorescence
Asynchronous HeLa were paraformaldehyde-fixed, permeablized, immunofluorescently labeled, counterstained with DAPI and imaged. Under these conditions this antibody gave a very strong signal. MeOH fixed samples were also evaluated and produced an equally strong signal.

Having reviewed this case, I would like to offer some suggestions to help optimize the results from ab150129. I would also appreciate if you can confirm some further details: Do you use a detergent such as Tween 20 in your washing buffer? Have you attempted to increase the number and duration of washes after antibody incubation? If so, did this have affect on the background? Have you attempted to further dilute the antibody to 1/1500, 1/2000 or greater? This antibody has not been pre-absorbed against mouse IgG, as such we cannot guarantee that we will be able to eliminate this reactive thought we hope that these suggestions will help reduce this. Abcam does offer a number of AlexaFluor 488 antibodies which have been pre-absorbed to ensure low species cross-reactivity including ab150133 which has been pre-absorbed against chicken, human, mouse, pig, rabbit and rat.
