General notes
ab227049 is the carrier-free version of ab215199.
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.

Target
-
Function
Binds to heparin. Induces cell attachment and spreading and plays a role in cell adhesion. May play a role in extracellular matrix mineralization. -
Tissue specificity
Widely expressed with highest levels in aorta, stomach, lower gastrointestinal tract, placenta, uterus and breast. Up-regulated in epithelial ovarian tumors. Not expressed in normal ovaries. Also highly expressed at the tumor periphery of lung carcinoma tissue but not within the tumor. Overexpressed in breast cancers. -
Sequence similarities
Contains 1 EMI domain.
Contains 4 FAS1 domains. -
Post-translational
modificationsGamma-carboxyglutamate residues are formed by vitamin K dependent carboxylation. These residues are essential for the binding of calcium. -

Immunohistochemical analysis of paraffin-embedded Human breast carcinoma tissue labelling Periostin with ab215199 at 1/1000 dilution (0.516 μg/ml) followed by a Goat Anti-Rabbit IgG H&L (HRP polymer) (ab214880) at a Ready to use dilution. Positive staining on extracellular matrix of human breast carcinoma. The section was incubated with ab215199 at 4°C overnight. Counterstained with Hematoxylin.
Secondary antibody only control: Secondary antibody is Goat Anti-Rabbit IgG H&L (HRP polymer) (ab214880) at Ready to use dilution.
Heat mediated antigen retrieval was performed using ab93684 (Tris/EDTA buffer, pH 9.0).
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab215199).
