UNC5B(399‐945aa)‐3Flag overexpression lentivirus and UNC5B(412‐945aa)‐3Flag overexpression lentivirus were synthesized by Obio Technology Co. Ltd. Tables 1 and 2 indicated the composition reports. Full‐length UNC5B‐Flag overexpression lentivirus was purchased from GenePharm Co. Ltd. The Lipofectamine 3000 Reagent (Life Technologies Co. Ltd.) was used for these plasmids and related transfection.
Antibodies against UNC5B (ab104871, ab54430), caspase‐3 (ab179517), mutant P53 (ab32049) and BCL‐2 (ab32124) were purchased from Abcam. Antibodies against cleaved PARP (D64E10), S6 Ribosomal Protein (5G10), UNC5B (D9M7Z) and beta‐actin (3700S) were obtained from Cell Signaling Technology (CST). Antibodies against Fibronectin, beta‐catenin, vimentin, N‐CA and E‐CA were also obtained from the Epithelial‐Mesenchymal Transition (EMT) Antibody Sampler Kit (9782T, CST). Antibody against FLAG (F1804) was obtained from Sigma‐Aldrich Co. Ltd. Antibody against P53 (21891‐1) was purchased from Proteintech Co. Ltd. UNC5B (ab54430, Abcam) was used for immunofluorescence and flow cytometry. UNC5B (D9M7Z) was used as a mixture reagent in Co‐IP. Universal Magnetic Co‐IP Kit (54002, Active Motif) was purchased from Active Motif Co. Ltd. Fast silver staining kit (P0017S, Beyotime) was purchased from Beyotime Co. Ltd.

Immunofluorescence Analysis of Adipose Tissue

Check if the same lab product or an alternative is used in the 5 most similar protocols
White adipose tissue was excised, fixed in formalin overnight, embedded in paraffin and sectioned. The immunofluorescence analysis of netrin-1 (1:200, AF1109; R&D systems), caveolin-1 (1:500, 610059; BD bioscience), Unc5b (1:200, ab54430; Abcam), F4/80 (1:500, MCA497GA; Abd serotec), CD68 (1:500, MCA1957; Abd serotec) was conducted after deparaffinization as described previously61 (link). Secondary antibodies were then applied (Alexa Fluor-568, A11011; Alexa Fluor-488, A11006; 1:500 Invitrogen). Netrin-1 and Unc5b staining was amplified using the biotin conjugated antibodies (1:100, BA-2000 and BA-9500; Vector Laboratories) followed by streptavidin conjugated AMCA (1:200, Sa-5008; Vector Laboratories) staining. Sections were mounted and visualized using a Nikon Eclipse microscope.

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.
