This product is a recombinant rabbit monoclonal antibody.
Our Abpromise guarantee covers the use of ab126712 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/1000 - 1/10000. Detects a band of approximately 23 kDa (predicted molecular weight: 23 kDa).|
|IHC-P||1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
See protocols (link: http://www.abcam.com/protocols/ihc-antigen-retrieval-protocol).
|Flow Cyt||Use at an assay dependent concentration.|
|ICC/IF||1/50 - 1/200.|
ab126712 staining RAB7 in the human cell line A431 (human epidermoid carcinoma) by flow cytometry. Cells were fixed with 4% paraformaldehyde and the sample was incubated with the primary antibody at a dilution of 1/80. A goat anti rabbit IgG (Alexa Fluor® 488) at a dilution of 1/2000 was used as the secondary antibody.
Isoytype control: Rabbit monoclonal IgG (Black)
Unlabelled control: Cell without incubation with primary antibody and secondary antibody (Blue)
Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: RAB7 knockout HAP1 cell lysate (20 µg)
Lane 3: A431 cell lysate (20 µg)
Lane 4: Human fetal brain tissue lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab126712 observed at 24 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab126712 was shown to recognize RAB7 when RAB7 knockout samples were used, along with additional cross-reactive bands. Wild-type and RAB7 knockout samples were subjected to SDS-PAGE. ab126712 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/10000 and incubated overnight at 4°C. Blots were developed withGoat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging.
Immunohistochemical staining of paraffin-embedded human bladder carcinoma sections labelling RAB7 with purified ab126712 at dilution of 1/70. The secondary antibody used was ab97051; a goat anti-rabbit IgG H&L (HRP) at dilution of 1/500. The sample was counter-stained with hematoxylin. Antigen retrieval was performed using EDTA Buffer; pH 9.0. PBS was used instead of the primary antibody as the negative control and is shown in the inset.
Immunohistochemical analysis of paraffin-embedded Human colon adenocarcinoma tissue labelling Rab7A with unpurified ab126712 at dilution of 1/50.
Immunocytochemistry/immunofluorescence staining of 4% paraformaldehyde fixed; 0.1% triton X 100 permeabilized HT-29 (human colorectal adenocarcinoma) cells with purified ab126712 at dilution of 1/100. The secondary antibody used was Alexa Fluor® 488; goat anti-rabbit IgG (ab150077) at a dilution of 1/1000. Nucleus was counter-stained with DAPI (blue). ab7291, a mouse anti-tubulin antibody (1/1000) was used to stain tubulin along with ab150120 (AlexaFluor®594 goat anti-mouse secondary, 1/1000) shown in the top right hand panel. The negative controls are shown in the bottom middle and right hand panels- for negative control 1 rabbit primary antibody and anti-mouse secondary antibody (ab150120) was used. For negative control 2 mouse primary antibody (ab7291) and anti-rabbit secondary antibody (ab150077) was used.
