Vector SG and ImmPACT^® SG HRP substrates produce blue-gray reaction products that can be used as a single label or as a second color for multiple antigen labeling. With the aid of imaging systems and software, the spectral profile of both chromogens can be distinguished from other enzyme substrates in applications where antigens are co-localized. Sections stained with either substrate also can be viewed by darkfield or electron microscopy. Vector SG and ImmPACT SG substrates can be used for both manual and automated staining methods. Stained sections can be dehydrated, cleared, and permanently mounted.

Vector SG Substrate Kit contains stock solutions in convenient dropper bottles. The sensitivity of Vector SG subsrate is equivalent to AEC. This product can also be used on blots. The kit provides all of the necessary reagents to prepare about 300 ml of working solution. When stored at 4 °C, this kit is stable for one year.
