Product Description for Interleukin-9 (IL-9)
Properties for Interleukin-9 (IL-9)
|Product Category||Proteins & Growth Factors|
|Molecular weight||14 kDa|
|PDF datasheet||View Datasheet|
|Manufacturer||Acris Antibodies GmbH|
|Material safety datasheet||MSDS for Proteins (de)|
|Purity||> 98 % Purified by proprietary chromatographic techniques, sterile filtered, purity > 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
|Add. information||Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 0.6 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a standard solution of IL-9 as a Reference Standard.
|Background||Factor that is thought to be a regulator of hematopoiesis. It has been shown to enhance the growth of human mast cells and megakaryoblastic leukemic cells as well as murine helper t-cell clones. IL-9 is a glycoprotein with a molecular weight of 32-39 that is derived from T-cells, and maps to human chromosome 5.|
|Concentration||1 mg/ml (lyophil.)|
|Storage||Lyophilized product is stable at room temperature for one month, should be stored desiccated below -20 °C. Upon reconstitution it should be stored at 2 - 8 °C up to one week and for future use below -20 °C. For long term storage it is recommended to add a carrier protein (0.1 % HSA or BSA). Avoid repeated freezing and thawing.
Shelf life: one year from despatch.
