Product name: MTCO1 Monoclonal Antibody (1D6E1A8)
Antibody type: Monoclonal
Antigen: Other
Description: For best results with this antibody in Western blot, do not boil samples before loading onto the gel. Boiling of the sample will cause a loss of signal. Hydrophobic intrinsic membrane proteins such as the core mtDNA-encoded proteins of the mitochondrial OXPHOS complexes tend to run faster in SDS-PAGE than predicted by their amino acid composition. This is likely due to incomplete unfolding of the protein and a more negative charge:mass ratio. In Western blot applications, this antibody detects a band at approximately 40 kDa (predicted MW: 57 kDa). In mouse liver lysate a specific band below 37 kDa was detected. Recommended positive controls: ICC/IF - Pig retinal pigment epithelial cells, rat cerebellum primary cells IHC (P) - Human skeletal muscle and colon tissue, rat pancreas tissue, pig smooth muscle tissue WB - Mouse, human, bovine and rat heart mitochondria lysate Flow - HEK-293 cells Recommended long term storage at -20°C.

Experimental details: Immunofluorescence analysis of MTCO1 was performed using 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with MTCO1 Monoclonal Antibody (1D6E1A8) (Product # 459600) at 5 µg/mL dilution in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32766), (1:2000 dilution), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b:Blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing mitochondrial localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60x magnification.

Representative images showing SNAP23 colocalization with the plasma membrane marker dystrophin (A), mitochondrial marker COX (B), and IMTG staining using oil red O (C). All images were obtained using a 63x oil objective of a confocal microscope. Bar = 30 mu m. Pearson's correlation coefficients are shown on the merged images (mean +- SEM). The Pearson's correlation coefficients of the nonmatched pairs of images were; SNAP23 and Dystrophin ( r = 0.007 +- 0.003); SNAP23 and IMTG ( r = 0.000 +- 0.003); SNAP23 and COX ( r = 0.006 +- 0.005). All these values were significantly lower ( P < 0.05) than the matched image pairs demonstrating that the colocalization detected was not due to chance.

Representative confocal micrographs of mouse primary RPE (A-F) and ARPE-19 (G-L) monolayers plated on Transwells(r) and labeled with antibodies to DJ-1 (A, D, G, J) and COX IV (B, E, H, K).

Upon oxidative stress induced by incubation with 400 uM H 2 O 2 for 1 hr, DJ-1 staining is increased both in the mouse primary (D) and ARPE-19 (J) cultures.

Colon PPARGC1A (PGC-1alpha) expression for f PROTECT cohort, h RISK cohort in (transcripts per million (TPM) values), and for j adult UC cohort (GSE59071 12 ) in normalized values was plotted after stratifying the samples as indicated. g , i , k Krebs cycle TCA gene signature PCA PC1 for the above cohorts is plotted, samples are stratified as indicated. l Representative rectal MT-CO1 and COX5A immunohistochemistry (complex IV) for Ctl ( n = 14), inactive ( n = 10), and active UC ( n = 11) with moderate Mayo endoscopic subscore and moderate PUCAI.

Experimental details: Fig. 4 Mitochondrial alterations in EBS-MD muscle. a Skeletal muscle specimens from a healthy control and EBS-MD patients were histologically double-stained for SDH and COX. Note the presence of ""rubbed-out"" areas ( arrows ), and the presence of COX-negative fibers in patient 3 ( arrowheads ). Scale bar: 50 mum. b Confocal imaging of mitochondrial respiratory complex IV-stained skeletal muscle specimens from a healthy control and EBS-MD patients. Panels i-iv are magnifications of the boxed areas in panel b. Note the reduced staining intensity in all EBS-MD samples. Scale bars: 50 mum ( b ), 25 mum (panels i-iv). c Immunoblotting of cell lysates prepared from EBS-MD patients and three healthy controls using antibodies for mitochondrial respiratory complex II or V. alpha-Actinin was used as loading control. d Signal intensities of respiratory complex II or V protein bands as shown in ( c ) were densitometrically measured and normalized to the total protein content (assessed by alpha-actinin staining). Healthy controls ( dashed line ) are set to 100 %. Mean values +- SEM, 3 replicates

Experimental details: Figure 1 Cultured and Labelled mesenchymal stem cells morphology by light microscope without superparamagnetic iron oxide (SPIO) labeling (x40) ( A ) and with SPIO labeling after staining with Prussian blue (x40) ( B ). Transmission electron microscopic examination ( C ) x5600 & ( D ) x11000, showing labeled cells with iron particles appear as black aggregates among numerous round endosomes within the cytoplasm (arrows). The nucleus (N) is convoluted, with prominent euchromatin and peripheral heterochromatin, a conspicuous nucleolus (Nu) is also seen. Homing of the SPIO-labelled transplanted MSCs into their niche evident by immunohistochemical (IHC) staining ( E ) & Prussian blue staining ( F ) of the recipient liver where IHC using the anti-OxPhos complex IV subunit I monoclonal antibody showing areas that were negative for cytochrome C oxidase located either in close proximity to, or in direct contact with, the portal tract region (arrows; X40 magnification). Prussian blue staining showing bluish iron particles distributed intracellularly in the same region as the cytochrome C oxidase-deficient patches (arrows; X40 magnification). Successful macrophage depletion from the liver shown by IHC, the normal distribution of Kupffer cells is evident in nondepleted liver ( G ) with significant reduction after using clodronate liposome with very few positive anti f4/80 ab cells in the hepatic parynchyma x40 ( H ).
