siRNA / miRNA gene silencing Human - LAD2 PU.1/SPI1

miRNA is the inherent gene silencing machinery which can have more than one mRNA target, whereas siRNA can be designed to target a particular mRNA target. By design, both siRNA and miRNA are 20-25 nucleotides in length. The target sequence for siRNAs is usually located within the open reading frame, between 50 and 100 nucleotides downstream of the start codon. There are two ways in which cells can be transfected with desired RNAi: 1. Direct transfection (with calcium phosphate co-precipitation or cationic lipid mediated transfection using lipofectamine or oligofectamine), and 2. Making RNAi lentiviral constructs (followed by transformation and transduction). Lentiviral constructs are time consuming, but provide a more permanent expression of RNAi in the cells, and consistent gene silencing. Direct transfection of oligonucleotides provides temporary genetic suppression. Traditional methods like calcium phosphate co-precipitation have challenges like low efficiency, poor reproducibility and cell toxicity. Whereas, cationic lipid-based transfection reagents are able to overcome these challenges, along with applicability to a large variety of eukaryotic cell lines. When using oligos, the ideal concentration lies between 10-50nM for effective transfection.

	PU.1 siRNA (Stealth Select RNAi, HSS144058, HSS144060, and HSS186060), GATA1 siRNA (HSS142150, HSS142151, and HSS142152), GATA2 siRNA (HSS104003, HSS104004, HSS178122), c-kit siRNA (HSS105821), and control siRNA (Stealth RNAi Negative Universal Control Lo GC, Med GC, and Hi GC [12935-200, 300, and 400]) were purchased from Invitrogen (Carlsbad, CA). Transfection of siRNA was performed, as described previously (14). Briefly, 10 (or 1) ml 20 mmol/L siRNA was introduced into 2 3 106 (or 2 3 105) LAD2 cells or primary mast cells with a Neon 100 ml kit (or a Neon 10 ml kit) using a Neon transfection system (Invitrogen) set at Program 16 (for LAD2) or 5 (for primary mast cells).
