30,000+ siRNAs (HY-RS)

The pre-designed siRNA set contains 3 siRNAs targeting the gene of interest, a negative control, a positive control, and a FAM-labeled negative control.
MCE guarantees that when the transfection efficiency exceeds 80%, at least one siRNA will silence the target mRNA by at least 70%. Otherwise, we will synthesize 3 new siRNAs free of charge.
Component Quantity Description
siRNA-1 5 nmol Three siRNAs are designed to target different regions of the target gene.
siRNA-2
siRNA-3
siRNA Negative Control 5 nmol There is no homology between the negative control sequence and the target gene sequence.
FAM-labeled siRNA Negative Control 5 nmol It is used to assess transfection efficiency.
GAPDH siRNA Positive Control 5 nmol It is used to confirm that the RNAi experiments were performed correctly.
