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.

Ordering & Configuration
