Rabbit anti vcam 1

Manufactured by Cell Signaling Technology
Sourced in United States

Rabbit anti-VCAM-1 is a primary antibody that specifically recognizes the vascular cell adhesion molecule-1 (VCAM-1) protein. VCAM-1 is a cell surface receptor that mediates the adhesion of leukocytes to the vascular endothelium. This antibody can be used to detect and quantify VCAM-1 expression in various experimental systems.

Cells were collected in 1× RIPA buffer containing 1 mM PMSF and sonicated for 10 s. Protein concentrations were measured using the bicinchoninic acid (BCA) assay (Pierce). Equal amounts of protein (20 μg/lane) were loaded onto 4%–15% precast protein gels (Bio-Rad) and transferred to polyvinylidene difluoride (PVDF, Bio-Rad) membranes. Membranes were blocked for 1 hr with TBS/0.1%-Tween buffer plus 5% (w/v) non-fat dried milk and incubated overnight at 4°C with primary antibodies dissolved in blocking buffer. Membranes were incu-bated with secondary antibodies for 1 hr and developed using a Pierce® ECL Western blotting detection kit (Thermo Scientific) and a ChemiDoc XRS System (Bio-Rad). Image lab software was used to quantitate Western blot signals. The following primary antibodies were used in this study: mouse anti-CaMKK β (1:200; Santa Cruz Biotechnology), rabbit anti-SIRT1 (1:1000; Cell Signaling), rabbit anti-phospho-SIRT1 (1:1000; Cell Signaling), rabbit anti-phospho-CAMKIV (1:1000; Abcam), rabbit anti-eNOS (1:1000; Cell Signaling), rabbit anti-VCAM-1 (1:1000; Cell Signaling), rabbit anti-CD54/ICAM1 (1:1000;Cell Signaling) and mouse anti-β-actin (1:5000; Sigma-Aldrich). HRP (horseradish peroxidase)-conjugated anti-rabbit IgG (1:2000; Vector Laboratories) and HRP-conjugated anti-mouse IgG (1:2000; Vector Laboratories) were used as secondary antibodies.

Western blotting was done, following the previously mentioned method [18 ,19 (link)]. Hippocampal tissues were extracted by homogenization using lysis buffer (pH, 7.6) After separating 30 μg protein using sodium dodecyl sulfate-polyacrylamide gel electrophoresis, the protein was moved to a nitrocellulose membrane (GE Healthcare Bio-Sciences, Pittsburgh, PA, USA). The membrane was treated with 5% skimmed milk powder (BD Difco, Detroit, MI, USA) for blocking, and incubated with 0.1% Tween-20 (Sigma Aldrich Co.) for 1 hour at room temperature. The membrane was treated with the primary antibodies such as rabbit anti-VCAM-1 (1:1,000, Cell Signaling Technology), rabbit anti-ICAM-1 (1:1,000, Cell Signaling Technology), mouse anti-TNF-α (1:1,000; Santa Cruz Biotechnology, Santa Cruz, CA, USA), rabbit anti-IL-6 (1:1,000; Santa Cruz Biotechnology), and mouse anti-IL-1β (1:1,000; Santa Cruz Biotechnology). Membranes were subsequently incubated for l hour with peroxidase-tagged secondary antibodies. Enhanced chemiluminescence detection kit (DoGen, Seoul, Korea) was used for visualization of protein, and quantitative analysis of bands was calculated using Image-ProPlus program (Media Cybernetics, Rockville, MD, USA).

HUVECs pre-exposed to curcumin or vehicle were harvested at the end of a 4-hour-TNF- activation period and washed twice with ice-cold PBS. Total proteins were extracted using lysis buffer containing 50 mmol/L Tris pH 7.8, 150 mmol/L NaCl, 0.5% sodium deoxycholate, 1% NP40, antiprotease and anti-phosphatase. Protein concentration was determined using BCA protein assay reagent Kit (Interchem). Lysates were loaded onto a 10% SDS-polyacrylamide gel for electrophoresis and then transferred onto immobilon-P membrane (GE Healthcare). The membrane was incubated in 5% (wt/vol) dried milk protein in TBS containing 0.05% Tween-20 for 1 hour, and then further reacted with primary antibodies: rabbit anti-iCAM (Santa Cruz, 1:1000), rabbit anti-vCAM-1 (1:1000, GTX), rabbit anti-NFB total (1:1000, Cell Signaling), rabbit anti-NFB phosphor-ser536 (1:1000, Cell Signaling), rabbit anti-IB total (1:1000, Cell Signaling) and rabbit anti-IB phosphor-ser32

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.
