What matters when choosing

Lipofectamine RNAiMAX is an Invitrogen reagent for siRNA and miRNA delivery. This guide compares its selected pack sizes and contents with Yeasen RNAiBoost 40807, which Yeasen markets as an RNAiMAX alternative. RNAiBoost includes a separate enhancer, while the referenced RNAiMAX product is supplied as a reagent vial.

Questions before switching products

How do the kit contents differ?

The referenced RNAiMAX pack contains a reagent vial. RNAiBoost includes the labelled reagent volume plus a separate enhancer. Compare the complete kit contents and follow the instructions for the product you select.

Section link

Is there manufacturer evidence in primary cells?

YEASEN lists siRNA examples in primary human umbilical vein endothelial cells (HUVEC) and bone marrow-derived macrophages (BMDM), alongside established cell models. Review the linked official examples for your model; these are not Direct Lab Supplies customer results.

Section link

Should I choose RNAiBoost or Booster for plasmid DNA or mRNA?

For plasmid DNA or mRNA, review Booster 40801 and its current manufacturer documentation. RNAiBoost 40807 is positioned for siRNA, miRNA and ASO delivery. A shared transfection label does not make the two product families interchangeable.

Section link

Does RNAiBoost use the same instructions as RNAiMAX?

Interchangeable instructions have not been established. Consult the current manual supplied by the manufacturer of the product you select, including its component requirements.

Section link

Does a manufacturer's comparison establish equivalent performance?

No. Manufacturer figures describe specific experiments. Direct Lab Supplies has not independently established equivalent results across cell types or applications.

Section link

How can a UK laboratory evaluate a Yeasen option?

Use the product page to review the manufacturer documents and request an evaluation sample or quotation. Sample format and availability are confirmed individually.
