Rabbit polyclonal anti-calretinin HB6494 staining interneurons and chicken polyclonal anti-GFAP a href="/anti-gfap-antibody-chicken-validab.html">HB6406 staining of astrocytes in the rat hippocampus. Calretinin was detected using an anti-rabbit biotin antibody (HB11036) followed by incubation with Streptavidin Janelia Fluor® 646 HB17045.
Method: Rat brains were dissected and fixed overnight in 4% PFA before then being incubated in 30% sucrose (in PBS) until sunk (approx. 48hrs). A freezing microtome was used to cut 40µm horizontal slices before sections were incubated in 1% NaBH4 for 30 minutes. Sections were blocked in 0.05M glycine, 2% BSA and 3% donkey serum before incubation overnight in anti-calretinin HB6494 (1:1,000 dilution) and anti-GFAP HB6406 (1:4000 dilution) at 4°C. This was followed by a two hour incubation with goat anti-rabbit biotin antibody (HB11036) at a dilution of 1:250 and goat anti-chicken Alexa Fluor™ 488 (Invitrogen) at a dilution of 1:300. Following three washes in PBST, sections were incubated with Streptavidin Janelia Fluor® 646 HB17045 at 1.0 µg/mL for 2 hours at room temperature. DAPI HB0747 was used at 1µg/ml to visualise cell nuclei. For more detail please see our IHC(IF) protocol . Images were captured using a Leica SP8 AOBS confocal laser scanning microscope attached to a Leica DM I8 inverted epifluorescence microscope. The image was captured 10x objective, 405nm (6.0% power, PMT: 725.1V gain), 488nm (2.18% power, Hyd: 22.9% gain) and 633nm (10.16% power, Hyd: 94.7% gain) laser lines in a z-stack (3.67µm spacing). The stack was flattened using a maximum Z projection in ImageJ (Schindelin et al., 2012. Nat Methods, 9(7), 676–682).

Negative control
While this antibody has been cross-adsorbed to reduce non-specific binding it is still often worthwhile to conduct a control experiment where the primary antibody is omitted to give confidence that the staining pattern observed is specific.
Storage & Handling
Storage instructions
-20°C then use reconstitution advice
Reconstitution advice
We recommend reconstituting with either:
dH2O and storing at 4°C
50:50 ratio of dH2O to glycerol and storing at -20°C
dH2O then aliquot and store at -80°C
Take care when opening as the precipitate is extremely light and can easily be lost if disturbed. When reconstituting make sure that the antibody is thoroughly dissolved by pipetting up and down before giving the antibody a brief spin at <10,000g to make sure that all material is recovered and at the bottom of the tube.
