Hieff Trans RNAiBoost is a reagent for siRNA, miRNA and ASO transfection in gene-silencing research. Each pack includes a separate enhancer.
Hieff Trans RNAiBoost is an RNAi-focused transfection reagent for siRNA, miRNA and ASO delivery. YEASEN reports greater than 90% target-gene silencing in its tested systems, including selected difficult-to-transfect primary cells. This is a manufacturer-reported result, not a universal knockdown guarantee. The formulation is described as compatible with serum and antibiotics and is supplied with a separate enhancer.

Its current manual lists siRNA, miRNA and ASO. For DNA or mRNA delivery, review Booster 40801 instead and confirm the required cell-model evidence.
No. YEASEN's stated RNAiBoost result is target-gene silencing in its tested systems. Knockdown, payload uptake and cell viability are different readouts.
