General notes
ab251554 is the carrier-free version of ab216575.
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-Obestatin antibody [EPR19972] - BSA and Azide free (ab251554)

All lanes : Anti-Obestatin antibody [EPR19972] (ab216575) at 1/1000 dilution

Lane 1 : GST and His-tagged human Appetite-regulating hormone, full length recombinant protein (aa1-117) at 0.005 µg
Lane 2 : His-tagged human Obestatin peptide (aa76-98)*5 at 0.005 µg
Lane 3 : His-tagged human Ghrelin peptide (aa24-51)*4 at 0.05 µg

Secondary
All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/100000 dilution

Predicted band size: 13 kDa
Observed band size: 13,38 kDa
why is the actual band size different from the predicted?

Exposure time: 1 second

This data was developed using ab216575, the same antibody clone in a different buffer formulation.

Blocking and dilution buffer: 5% NFDM/TBST.

Obestatin and Ghrelin are processed cleaved forms deriving from Appetite-regulating hormone. This product is specific to Obestatin.

Detecting Obestatin in endogenous tissues may require optimization.

This data was developed using ab216575, the same antibody clone in a different buffer formulation.Immunohistochemical analysis of paraffin-embedded human stomach tissue labeling Obestatin with ab216575 at 1/2000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) at a ready to use dilution. Cytoplasmic staining on endocrine cells of human stomach is observed [PMID: 18474938]. Counter stained with Hematoxylin. Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) at a ready to use dilution. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
