SmartGlow Safe Green Pre Stain, 1.0 mL

The E4500-PS is the SmartGlow Safe Green Pre Stain — gel-pre-stain reagent in a 1.0 mL volume at $129. Pre-stain workflow — added to molten agarose during gel pour, stain becomes incorporated throughout the gel matrix. Alternative workflow position to the E4500-LD Loading Dye + Stain ($129 — same price, loading-step incorporation).

Key Specifications

Why Pre Stain (Gel-Pour Incorporation)

Pre-stain workflow incorporates stain throughout the agarose matrix — alternative to loading-step stain incorporation:

• Uniform stain distribution across the gel
• Single-volume preparation — pre-stain added once at gel-pour, no per-sample reagent management at loading
• Cleaner loading wells — sample-loading uses standard loading dye without stain
• Pair with SmartBlue Blue LED transilluminator (E4000 / E4101) for no-UV visualization

Pick the E4500-PS when:

• Gel-pour-time stain incorporation matches the workflow preference
• Multi-sample casting batches — single pre-stain dose covers all samples in a gel
• Standard loading-dye workflow is established and operator wants to keep loading-dye step unchanged

Pick E4500-LD Loading Dye + Stain ($129) for loading-step incorporation — combines loading dye and stain in a single reagent.
