Analysis Note

ControlIncludes negative control normal mouse IgG antibody and control primers specific for the cDNA of human lincRNA SFPQ.

Application

Immunoprecipitation from RIP lysate:
Representative lot data.
RIP lysate from HeLa cells (~2 X 10E7 cell equivalents per IP) was subjected to immunoprecipitation using either 5 µg of a normal mouse IgG (Cat. #CS200621), or 5 µg of Anti-SUZ12 antibody (Cat. # CS203201).
20 percent of the precipitated proteins (lane 1: mouse IgG, lane 2: SUZ12) were resolved by electrophoresis, transferred to nitrocellulose and probed with anti-SUZ12 antibody (Cat. # CS203201, 1:1000). Proteins were visualized using One-Step™ IP-Western kit (GenScript Cat. # L00232)
Arrow indicates SUZ12 (Figure 2).

Western Blot Analysis:
Representative lot data.
Lysates from HeLa cells were resolved by electrophoresis, transferred to PVDF and probed with anti-SUZ12 (1:1,000 dilution).
Proteins were visualized using goat anti-mouse secondary antibody conjugated to HRP and chemiluminescence detection.
Arrow SUZ12 (~95 kDa) (Figure 3).

General description

SUZ12 is a polycomb group (PcG) protein. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. They probably act via the methylation of histones, rendering chromatin heritably changed in its expressibility. Component of the PRC2 complex, which methylates ′Lys-9′ and ′Lys-27′ residues of histone H3.

Quality

RNA Binding Protein Immunoprecipitation:
RIP Lysate prepared from HeLa cells (2 X 10E7 cell equivalents per IP) were subjected to immunoprecipitation using either 5 µg of a normal mouse IgG , or 5 µg of Anti-SUZ12 antibody and the Magna RIP^® RNA-Binding Protein Immunoprecipitation Kit (Cat. # 17-700).
Successful immunoprecipitation of SUZ12-associated RNA was verified by qPCR using RIP Primers lincSFPQ, (Figure 1)
Please refer to the Magna RIP™ (Cat. # 17-700) or EZ-Magna RIP™ (Cat. # 17-701) protocol for experimental details.

Specificity

SUZ12

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variabillity in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.
