Human paraffin-embedded tonsil tissue slices were prepared with a standard protocol of deparaffinization and rehydration. Antigen retrieval was done with Sodium Citrate H.I.E.R. 1X at 95°C for 40 minutes. Tissue was washed with PBS/0.05% Tween 20 twice for five minutes and blocked with 5% FBS and 0.2% gelatin for 30 minutes. Then, the tissue was stained with 10 µg/mL of anti-human PNAd (clone MECA-79) Biotin, and anti-human CD8a (clone C8/144B) Alexa Fluor® 647 (green) at 4°C overnight, followed by 2.5 µg/mL of Streptavidin Spark YG™ 570 (red) for two hours at room temperature. Nuclei were counterstained with DAPI (blue). The image was captured with a 10X objective. -
Mouse embryonic fibroblast NIH/3T3 cell line was fixed with 1% paraformaldehyde (PFA) for 10 minutes and blocked with 5% FBS for 30 minutes. Then the cells were stained with anti-mouse/human CD44 biotinylated antibody (clone IM7), followed by Streptavidin Spark YG™ 570 (red). Nuclei were counterstained with DAPI (blue). This image was captured with a 40X objective.

This streptavidin product is quality control tested by immunohistochemical staining on frozen tissue sections. The concentration provided is based upon molecular mass of streptavidin independent of any additional molecular mass that might be added by the Spark YG™ 570 conjugation. For immunohistochemistry, a concentration range of 2.5 - 5.0 µg/mL is suggested. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 2.5 - 5.0 µg/mL is suggested. For immunocytochemistry, a concentration range of 2.5 - 5.0 µg/mL is recommended. It is recommended that the reagent be titrated for optimal performance for each application.
* Spark YG™ 570 has a maximum excitation of 555 nm and a maximum emission of 570 nm. - Excitation Laser
