|Protein Name||Programmed cell death 1 ligand 1|
|Molecular Weight||33275 MW|
|Protein Function||Involved in the costimulatory signal, essential for T- cell proliferation and production of IL10 and IFNG, in an IL2- dependent and a PDCD1-independent manner. Interaction with PDCD1 inhibits T-cell proliferation and cytokine production. .|
|Tissue Specificity||Highly expressed in the heart, skeletal muscle, placenta and lung. Weakly expressed in the thymus, spleen, kidney and liver. Expressed on activated T- and B-cells, dendritic cells, keratinocytes and monocytes. .|
|Sequence Similarities||Belongs to the immunoglobulin superfamily. BTN/MOG family.|
|Subcellular Localization||Isoform 1: Cell membrane; Single-pass type I membrane protein.|
|Alternative Names||Programmed cell death 1 ligand 1;PD-L1;PDCD1 ligand 1;Programmed death ligand 1;B7 homolog 1;B7-H1;CD274;CD274;B7H1, PDCD1L1, PDCD1LG1, PDL1;|

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.,
