| Purity | Greater than 99.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. | Source | Escherichia Coli. |
| Phycical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | Shipping Condition | Shipped at Room temp. |
| Synonyms | Small inducible cytokine A1; CCL1; T lymphocyte-secreted protein I-309; chemokine (C-C motif) ligand 1; P500; SISe; TCA3; I-309; SCYA1. | ||
| Amino Acid Sequence | The sequence of the first five N-terminal amino acids was determined and was found to be Ser-Lys-Ser-Met-Gln. | ||
| Solubility | It is recommended to reconstitute the lyophilized I-309 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | ||
| Stability | Lyophilized I-309 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution CCL1 should be stored at 4°C between 2-7 days and for future use below -18°C . For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. | ||
| Biological Activity | The Biological activity is calculated by its ability to chemoattract human T cells at 10-100ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg. | ||
| Formulation | The CCL1 protein was lyophilized with no additives. | ||
Chemokine (C-C motif) ligand 1 (CCL1) is a small glycoprotein secreted by activated T cells that belongs to a family inflammatory cytokines known as chemokines. CCL1 attracts monocytes, NK cells, and immature B cells and dendritic cells by interacting with a cell surface chemokine receptor called CCR8. This chemokine resides in a large cluster of CC chemokines on human chromosome 17.
The Biological activity is calculated by its ability to chemoattract human T cells at 10-100ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg.
Lyophilized I-309 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C .
