Anti loxl2

Manufactured by Santa Cruz Biotechnology
Sourced in United States

Anti-LOXL2 is a laboratory reagent used for research purposes. It is an antibody that specifically binds to the LOXL2 protein, which is involved in the cross-linking of collagen and elastin in the extracellular matrix. The core function of Anti-LOXL2 is to enable the detection and study of LOXL2 in various experimental systems.

Protein Expression Analysis in Mouse Liver

LOXL2, YAP, and α-SMA protein expressions were analyzed using MSC-ex or BAPN-treated mouse tissue samples. Mouse tissue sections (4 µm thick) of formalin-fixed, paraffin-embedded liver specimens were deparaffinized in xylene and rehydrated in graded alcohol. Standard immunohistochemical procedures were performed on liver tissue sections using anti-LOXL2 (1:50; Santa Cruz Biotechnology, USA), anti-YAP (1:50; Bioworld, USA), or anti-α-SMA antibody (1:50; Bioworld, USA). Signals were visualized using 3, 3′-Diamino-benzidine tetrahydrochloride (Boster Biology, Wuhan, China). A brown membrane, cytoplasmic, and nuclear staining indicated a positive reaction according to different markers. The staining result of LOXL2, YAP, and α-SMA expression was determined by the percentage of positive cells by two investigators blinded to the data. Immunofluorescence staining was performed using anti-CD9 (1:100, Bioworld, USA), anti-LOXL2 (1:50), anti-YAP (1:50), or anti-α-SMA antibody (1:50). Negative controls with isotype IgG were run in parallel. Images were acquired using a laser scanning confocal microscope (Nikon, Tokyo, Japan).

Breast Cancer Cell Culturing and Characterization

Check if the same lab product or an alternative is used in the 5 most similar protocols
MDA-MB231 cells were cultured in DMEM medium and MCF-7 breast carcinoma cells (ATCC, USA) were cultured in a mixture of F-12K and DMEM media. Culture media were supplemented with 10% heat-inactivated fetal bovine serum (FBS) and 1% antibiotic. All cultures were maintained at 37°C in a humidified incubator in a 5% CO2 atmosphere. RPMI 1640 medium, bovine serum albumin, trypsin/ethylenediaminetetraacetic acid, FBS, and Antibiotic-Antimycotic 100× were purchased from Invitrogen (USA). Dimethyl sulfoxide (DMSO), 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), baicalein and anti-β-actin antibodies were purchased from Sigma Aldrich (USA). Anti-Slug, anti-vimentin, anti-E-cadherin, anti-GSK3β, anti-pGSK3β, anti-Akt, anti-pAkt antibodies and 5127S-mouse anti-rabbit IgG (conformation specific) antibody—which does not recognize the IgG heavy (50 kDa) or light (25 kDa) chain—were purchased from Cell Signaling Technology (USA). Anti-Snail, anti-LOXL-2, anti-ubiquitin antibodies and MG132 were purchased from Santa Cruz Biotechnology (USA). Polyvinylidene fluoride (PVDF) membranes for Western blotting were purchased from Millipore (USA).

For immunohistochemistry, aortas from 6-wk-old C57BL/6 mice were embedded in cryoblock medium (VWR International) on dry ice. Cryosections were incubated with anti-LOX (Abcam, Cambridge, MA, USA) or anti-LOXL2 (Santa Cruz Biotechnology, Dallas, TX, USA) before fixation with acetone and further processing with secondary antibodies coupled to Alexa Fluor fluorochromes (Thermo Fisher Scientific) as previously described in Bignon et al. (9 (link)).
Frozen aortas were pulverized on dry ice before lysis in 25 mM Tris (pH 7.5), 100 mM NaCl, 5 mM EDTA, and 1% Triton X-100 containing Protease Inhibitor Cocktail (MilliporeSigma). Samples were centrifuged for 30 min at 15,000 g, and pellets were solubilized in Laemmli buffer. Proteins of both lysates were separated by SDS-PAGE and electrotransfered to PVDF membranes for immunodetection of LOX, LOXL2 (Abnova), fibronectin (Merck), and actin (Abcam).

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.
