Biotin Tyramide Signal Amplification Kit - AF488
Product overview
| Name | Biotin Tyramide Signal Amplification Kit - AF488 |
| Biological description | Biotin Tyramide Signal Amplification Kit – AF488 enables immunofluorescent detection of low abundance targets with a bright and photostable fluorophore. Biotin Tyramide Signal Amplification Kits enhance signal through deposition of biotin tyramide on neighbouring molecules. Streptavidin AF488 detects biotin with extremely high affinity, resulting in increased sensitivity and signal detection.
This kit provides the reagents for 100 x 1mL reactions, with a protocol that can easily be adapted for immunohistochemistry (IHC), immunocytochemistry (ICC) and in situ hybridisation (ISH).

Images
Figure 1: Tyramide Signal Amplification enhances parvalbumin staining compared to fluorescent secondary antibody in the rat hippocampus.
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-parvalbumin HB6457 (1:4,000 dilution) at 4°C.
Sections were incubated with goat anti-mouse AF488 (Thermofisher) at 1:300 for two hours to detect parvalbumin (right hand side image).
Tyramide Signal Amplification Kit – AF488 (HB18560) was used to detect parvalbumin on the left hand side image. Sections were incubated with 4 µg/mL goat anti-mouse HRP antibody (Sigma) for two hours. Following three washes in PBST, sections were incubated with 1:1000 dilution of biotin tyramide, 0.003% hydrogen peroxide and 0.1% Tween20 in PBS for 15 minutes. The amplification reaction was quenched with stop solution for 10 minutes. Following three washes in PBST, sections were incubated with 1:1000 dilution of Streptavidin AF488 for 2 hours at room temperature. DAPI HB0747 was used at 1µg/ml to visualize cell nuclei. For more detail please see our IHC(IF) protocol and TSA protocol. Images were captured using a Leica DMI6000B inverted epifluorescence microscope. Images were captured using a 20x objective in a z-stack with exposures: DAP:11.851 ms, GFP: 193.136 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).

Solubility & Handling
| Storage instructions | -20°C |
| Reconstitution advice | To reconstitute Streptavidin AF488 (HB13531) we recommend reconstituting with either 100 µl of:
Take care when opening as the precipitate is extremely light and can easily be lost if disturbed. When reconstituting make sure that the streptavidin is thoroughly dissolved by pipetting up and down before giving the streptavidin a brief spin at <10,000g to make sure that all material is recovered and at the bottom of the tube. To reconstitute Biotin Tyramide (HB3262) add 100 µL of DMSO. Aliquot and store at -20°C. |
| Storage buffer | Streptavidin AF488 when reconstituted contains PBS with 0.05% sodium azide and 1% recombinant BSA. |
