Nlrp3 ab214185

Manufactured by Abcam
Sourced in United Kingdom, United States

NLRP3 (ab214185) is a recombinant protein that corresponds to a portion of the human NLRP3 protein. NLRP3 is a member of the NLR (nucleotide-binding domain, leucine-rich repeat) family of proteins and is involved in the formation of the NLRP3 inflammasome, a multiprotein complex that plays a role in the immune response.

Cells were lysed and total proteins were subjected to sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-PAGE), transferred to a polyvinylidene difluoride membrane (Millipore, Germany). The membrane was sequential incubated with primary antibody and secondary antibody (LI-COR Co., USA), then detected by ODYSSEY infrared imaging system (LI-COR Co. USA). The primary antibodies including caspase-1 (#24232), cleaved-caspase-1(#89332), IL-1β (#12242), NF-κB P65 (#8242), phospho-NF-κB P65 (#3033), IκBα (#4814), phospho-IκBα (#2859), cleaved-GSDMD (#50928), TNF-α (#11948) and IL-6 (#12912) were purchased from Cell Signaling Technology, USA; GSDMD (ab239377), IL-18 (ab71495) and NLRP3 (ab214185) antibodies were purchased from Abcam, UK.

Protein was extracted from RAW264.7 cells with RIPA buffer, containing 50 mM Tris-HCl (pH 7.4), 150 mM sodium chloride, 1% NP-40, 0.25% sodium deoxycholate, 1 mM EDTA, 1% protease inhibitors cocktail (78425, Pierce, Rockford, IL, USA), 1 mM PMSF (36978, Pierce), 1 mM sodium orthovanadate (S6508, Sigma Aldrich) and 50 mM sodium fluoride (S7920, Sigma Aldrich). Protein concentrations were determined using the BCA Protein Assay Kit (23227, Pierce). 40 μg of total protein was resolved by SDS-PAGE. The blots were probed with primary antibodies against (TLR4 (#ab13556) (1:2000), NLRP3 (#ab214185) (1:1000), (both from Abcam, Cambridge, MA, USA), ASC (#67824) (1:500), p-p65 (#3033) (1:1000), totalp65 (#8242) (1:1000), caspase-1 (#2225) (1:1000), pro-caspase-1 (#12242) (1:1000), cleaved caspase-3 (#9661) (1:1000) or GAPDH (#2118) (1:10000) (all from Cell Signaling Technology, Beverly, MA, USA).

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.
