AC knockdown cells were harvested 48 hours after transfection for analysis by western blot. Mcl-1S knockdown cells were re-plated to 2.5 × 105 cells per ml and treated with SACLAC 24 hours after electroporation. Control- and SACLAC-treated cells were harvested 48 hours after SACLAC treatment, corresponding to 72 hours after electroporation. HL-60/VCR cells were transduced with vectors expressing shRNA to target AC or GFP control as previously described (23 (link)).

ARID1A-BAF250a Silencing and HIV Latency

Check if the same lab product or an alternative is used in the 5 most similar protocols
Pre-designed siRNA pools targeting transcripts of the human ARID1a-BAF250a (L-017,263-00-0005) and non-target control siRNA pool (D-001,810-10-20) were purchased from Dharmacon (Dharmacon, Etten-Leur, The Netherlands). Small-interfering RNAs were delivered by nucleofection using Amaxa Nucleofector (Amaxa AG-Lonza, Cologne, Germany) as previously described (Rafati et al., 2011 ). Briefly, cells were split to 3 × 105 cells/ml one day before nucleofection. Five million cells were centrifuged at 200 g for 10 min at room temperature, re-suspended in 100 μl of solution R, and nucleofected with 2 μM siRNA using program O28. Nucleofected cells were re-suspended in 500 μl of pre-warmed, serum-free antibiotic-free RPMI at 37 °C for 15 min and then plated in 4 ml of pre-warmed complete media. Seventy-two hours post-nucleofection cells were treated with SAHA [350 nM] or Prostratin [100 nM]. LTR-driven GFP expression was assessed after 24 and 48 h after treatment by FACS. RNA and protein for RT-qPCR and Western blot analysis were isolated 96 h after nucleofection.

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.
