產(chǎn)品規(guī)格:5μg/20μg/1mg
Synonyms | Melanoma-derived growth regulatory protein precursor, Cartilage-derived retinoic acid-sensitive protein, CD-RAP, MIA. |
Introduction | The Melanoma Inhibitory protein (MIA) was identified as an inhibitor of in vitro growth of malignant melanoma cells. The protein contains a SH3 domain. MIA acts as a potent tumor cell growth inhibitor for malignant melanoma cells and some other neuroectodermal tumors, including gliomas, in an autocrine fashion. In a study of human melanoma cell lines with different metastatic capacity MIA mRNA expression appeared to be inversely correlated with pigmentation. MIA has been shown to represent a very sensitive and specific serum marker for systemic malignant melanoma that might be useful for staging of primary melanomas, detection of progression from localized to metastatic disease during follow-up, and monitoring therapy of advanced melanomas. |
Description | Melanoma Inhibitory Activity Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain consisting of 108 amino having a total molecular mass of 12237 Dalton. The MIA is purified by proprietary chromatographic techniques. |
Source | Escherichia Coli. |
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation | The protein was lyophilized from a concentrated (1.66mg/ml) solution containing 20mM Potassium-phosphate pH=7 and 150mM potassium chloride. |
Solubility | It is recommended to reconstitute the lyophilized Melanoma Inhibitory Activity in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions. |
Stability | Lyophilized MIA although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution MIA should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles. |
Purity | Greater than 95.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. |
Amino acid sequence | Agrees with the sequence of native MIA human with an addition N-terminal Methionine residue. MGPMPKLADRKLCADQECSSHPISMAVALQDYMAPDCRFLTIHRGQVV YVFSLKGRGRFLWGGSVQGDYYGDLAARLGYFPSSIVREDQTLKVDVKT DKWDFYCQ. |
Biological Activity | The biological activity is calculated by the inhibiting effect on the invasion of Mel In Tumor cells and found active in Mel In assay. |
Protein content | UV spectroscopy at 280 nm using the absorption coefficient of 19300 M-1cm-1 . |
Usage | ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals. |
