General notes
ab277949 is the carrier-free version of ab277942.
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
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

Western blot - Anti-SIX1 + SIX6 + Six3 + SIX2 antibody [EPR23608-2] - BSA and Azide free (ab277949)

All lanes : Anti-SIX1 + SIX6 + Six3 + SIX2 antibody [EPR23608-2] (ab277942) at 1/1000 dilution

Lane 1 : A-204 (human muscle rhabdomyosarcoma) whole cell lysate
Lane 2 : Caco-2 (human colorectal adenocarcinoma epithelial cell) whole cell lysate

Lysates/proteins at 40 µg per lane.

Secondary
All lanes : Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) at 1/50000 dilution

Predicted band size: 32 kDa
Observed band size: 36 kDa
why is the actual band size different from the predicted?

This data was developed using ab277942, the same antibody clone in a different buffer formulation.

Blocking and diluting buffer and concentration: 5% NFDM/TBST.

The molecular weight observed is consistent with what has been described in the literature (PMID:31438963).

Negative control: Caco-2.

Lysate loaded onto lane 1 was made freshly and used in WB immediately to minimize protein degradation.

Exposure time: 37 seconds.
