The largest database of trusted experimental protocols

Scramble control sirna

Manufactured by OriGene
Sourced in United States

The Scramble (control) siRNA is a laboratory tool used in RNA interference (RNAi) experiments. It serves as a negative control to help researchers evaluate the specificity of their target gene silencing experiments. The Scramble siRNA sequence does not target any known gene and is designed to have minimal impact on cellular processes, providing a baseline for comparison against specific gene knockdown effects.

5 protocols using scramble control sirna

1

Silencing TLR4 in THP-1 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
THP-1 cells were transfected separately with TLR4-siRNA (30 nM; OriGene Technologies, Inc. MD, USA), scramble (control) siRNA (30 nM; OriGene Technologies, Inc. MD, USA, USA) and pmaxGFP (0.5μg; Amaxa Noclecfector Kit V for THP-1, Lonza). Transfection experiments were carried out using Amaxa Electroporation System (Amaxa Inc., Germany), according to the manufacturer’s protocol [13 (link)]. Effective suppression of constitutive TLR4 expression in THP-1 cells transfected with specific gene-targeted siRNA was confirmed by real time RT-PCR.

ACSL1 Knockdown in MDA-MB-231 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
MDA-MB-231 cells were washed and re-suspended in 100 μL of nucleofector solution provided with the Amaxa Nucleofector Kit V and transfected separately with siRNA-ACSL1 (30 nM; OriGene Technologies, Inc., Rockville, MD, USA), scramble (control) siRNA (30 nM; OriGene Technologies, Inc., Rockville, MD, USA), and pmaxGFP (0.5 μg; Amaxa Nucleofector Kit V for MDA-MB-231 cells, Lonza, Basel, Switzerland). All transfection experiments were performed with an Amaxa Cell Line Nucleofector Kit V for MDA cells (Lonza, Basel, Switzerland) using an Amaxa Electroporation System (Lonza, Basel, Switzerland) according to the manufacturer’s protocol [37 (link)]. After 36 h of transfection, cells were treated with TNFα for 24 h. Cells were harvested for RNA isolation and staining study. ACSL1 gene knockdown level was assessed by real-time PCR using ACSL1 gene specific primer probes.

Monocytes were washed and resuspended in 100 ul of nucleofector solution provided with the Amaxa Noclecfector Kit V and transfected separately with siRNA-CERK (30nM; OriGene Technologies, Inc. MD, USA), scramble (control) siRNA (30nM; OriGene Technologies, Inc. MD, USA, USA), and pmaxGFP (0.5 ug; Amaxa Noclecfector Kit V for THP-1, Lonza). All transfection experiments were performed with Amaxa Cell Line Nucleofector Kit V for monocytic cells(Lonza, Germany) by using Amaxa
Electroporation System (Amaxa Inc, Germany) according to the manufacturer's protocol 16 . After 36 hours of transfection, cells were treated with TNF-α for 2 hours. Cells were transfected with 20 nM of the siRNA using Viromer Blue (lipocalyx, Halle, Germany) as per manufacture's instruction. Cells were harvested for RNA isolation and staining study. CERK gene knock down level was assessed by Real Time-PCR using CERK gene specific primer (CERK: Assay ID: Hs00368483; ThermoFisher Sceintific).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
