|Protein Name||Leukocyte surface antigen CD47|
|Molecular Weight||35214 MW|
|Protein Function||Has a role in both cell adhesion by acting as an adhesion receptor for THBS1 on platelets, and in the modulation of integrins. Plays an important role in memory formation and synaptic plasticity in the hippocampus (By similarity). Receptor for SIRPA, binding to which prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells. Interaction with SIRPG mediates cell-cell adhesion, enhances superantigen-dependent T-cell-mediated proliferation and costimulates T-cell activation. May play a role in membrane transport and/or integrin dependent signal transduction. May prevent premature elimination of red blood cells. May be involved in membrane permeability changes induced following virus infection. .|
|Tissue Specificity||Very broadly distributed on normal adult tissues, as well as ovarian tumors, being especially abundant in some epithelia and the brain.|
|Subcellular Localization||Cell membrane ; Multi-pass membrane protein .|

"This antibody gives strong membrane staining"
--Peter J. Thompson, UCSF Diabetes Center, Postdoctoral Scholar
Applications IHC-Paraffin, IHC-cryo Sample NOD/ShiLtJ mouse pancreas sections, formalin-fixed paraffin embedded Detection Zeiss Apotome widefield fluorescence microscope
"CD47 is broadly expressed in many cell types. This antibody gives strong membrane staining throughout many of the beta cells (Insulin-positive) in the immune cell infiltrated islets of NOD mice at age 12 weeks."
1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands
3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.
4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
