Figure 1. Parvalbumin and Calretinin expressing interneurons in the rat hippocampus.
Rat hippocampus stained with HB6457 to detect Parvalbumin and HB6494 to detect Calretinin. Parvalbumin was detected using an anti-mouse biotin antibody followed by incubation with Streptavidin Janelia Fluor® 525 HB15382.
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 Parvalbumin HB6457 (1:1000 dilution) and Calretinin HB6494 (1:4000 dilution) at 4°C. This was followed by a two hour incubation with goat anti-mouse biotin antibody (HB11345), at a dilution of 1:250 and goat anti-rabbit Dylight™ 650 (Thermofisher) at a dilution of 1:300. Following three washes in PBST, sections were incubated with Streptavidin Janelia Fluor® 525 HB15382 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 DMI6000B inverted epifluorescence microscope. Images were captured as a tilescan using a 20x objective in a z-stack with exposures: A4: 57.803 ms, Y3: 599.044 ms, Y5 599.044 ms.
Stacks were deconvolved using Huygens professional then 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.
