General notes
ab172889 is the carrier-free version of ab108529.
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.
Mouse, Rat: We have preliminary internal testing data to indicate this antibody may not react with these species. Please contact us for more information.

Tissue specificity
Expressed in placenta, kidney, thymus, testis, ovary and intestine. -
Sequence similarities
Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. SNF1 subfamily.
Contains 1 KA1 (kinase-associated) domain.
Contains 1 protein kinase domain. -
Post-translational
modificationsAutophosphorylated. Thr-478 phosphorylation during mitosis promotes interaction with PPP1R8. -

All lanes : Anti-MELK antibody [EPR3981] (ab108529) at 1/1000 dilution
Lane 1 : HCT116 cell lysate
Lane 2 : MELK knockout HCT116 cell lysate
Lysates/proteins at 20 µg per lane.
Performed under reducing conditions.
Predicted band size: 75 kDa
Observed band size: 75 kDaThis data was developed using the same antibody clone in a different buffer formulation (ab108529).
Lanes 1 - 2: Merged signal (red and green). Green - ab108529 observed at 75 kDa. Red - loading control ab8245 (Mouse anti-GAPDH antibody [6C5]) observed at 37kDa.
ab108529 was shown to react with MELK in wild-type HCT116 cells in western blot with loss of signal observed in MELK knockout cell line ab266896 (MELK knockout cell lysate ab257537). Wild-type and MELK knockout HCT116 cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3% milk in TBS-T (0.1% Tween®) before incubation with ab108529 and ab8245 (Mouse anti-GAPDH antibody [6C5]) overnight at 4°C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. Blots were incubated 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 in 20000 dilution for 1 hour at room temperature before imaging.

This data was developed using ab108529, the same antibody clone in a different buffer formulation.
Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: MELK knockout HAP1 cell lysate (20 µg)
Lane 3: HeLa cell lysate (20 µg)
Lane 4: HCT116 cell lysate (20 µg)
Lanes 1 - 4 Merged signal (red and green). Green - ab108529 observed at 75 kDa. Red - loading control, ab8226, observed at 42 kDa.
ab108529 was shown to recognize MELK when MELK knockout samples were used, along with additional cross-reactive bands. Wild-type and MELK knockout samples were subjected to SDS-PAGE. ab108529 and ab8226 (loading control to beta Actin) were both diluted 1/1000 and incubated overnight at 4°C. 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 1/10 000 dilution for 1 h at room temperature before imaging.
