特記事項
ab240079 is the carrier-free version of ab133734.
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.
This product is a recombinant monoclonal antibody, which offers several advantages including:
- - High batch-to-batch consistency and reproducibility
- - Improved sensitivity and specificity
- - Long-term security of supply
- - Animal-free production
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

機能
Plays a role in pre-mRNA splicing and in the regulation of alternative splicing events. Binds to the polypyrimidine tract of introns. May promote RNA looping when bound to two separate polypyrimidine tracts in the same pre-mRNA. May promote the binding of U2 snRNP to pre-mRNA. Cooperates with RAVER1 to modulate switching between mutually exclusive exons during maturation of the TPM1 pre-mRNA. -

All lanes : Anti-PTBP1 antibody [EPR9048(B)] (ab133734) at 1/10000 dilution
Lane 1 : Wild-type HeLa cell lysate
Lane 2 : PTBP1 knockout HeLa cell lysate
Lysates/proteins at 20 µg per lane.
Performed under reducing conditions.
Predicted band size: 57 kDa
Observed band size: 57 kDaThis data was developed using the same antibody clone in a different buffer formulation (ab133734).
Lanes 1- 2: Merged signal (red and green). Green - ab133734 observed at 57 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.
ab133734 was shown to react with PTBP1 in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab265155 (knockout cell lysate ab257614) was used. Wild-type HeLa and PTBP1 knockout HeLa cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab133734 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) overnight at 4°C at a 1 in 10000 dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye®800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye®680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Intracellular Flow Cytometry analysis of A549 (Human lung carcinoma epithelial cell) cells labeling PTBP1 (red) with purified ab133734 at a 1/2000 dilution (1ug/mL). Cells were fixed with 4% paraformaldehyde and permeabilized with 90% methanol. A goat anti rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody at a 1/2000 dilution. Black - Rabbit monoclonal IgG (Black) (ab172730). Blue (unlabeled control) - Cell without incubation with primary antibody and secondary antibody (Blue).
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab133734).

All lanes : Anti-PTBP1 antibody [EPR9048(B)] (ab133734) at 1/10000 dilution
Lane 1 : Wild-type HAP1 whole cell lysate
Lane 2 : PTBP1 knockout HAP1 whole cell lysate
Lysates/proteins at 20 µg per lane.
Predicted band size: 57 kDaLanes 1 - 2: Merged signal (red and green). Green - ab133734 observed at 57 kDa. Red - loading control, ab9484, observed at 37 kDa.
ab133734 was shown to recognize PTBP1 in wild-type HAP1 cells as signal was lost at the expected MW in PTBP1 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and PTBP1 knockout samples were subjected to SDS-PAGE. Ab133734 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/10000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab133734).
