E. coli-Derived Recombinant Human EMAP-II
This antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 5.0% w/v trehalose with no calcium, magnesium, or preservatives present.
Storage and Handling
The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Applications and Recommended Usage?
Quality Tested by Leinco
Western Blotting: To detect Human EMAP-II this polyclonal antibody can be used at a concentration of 0.5 µg/ml. This polyclonal antibody should be used in conjunction with compatible second-step reagents such as PN:G505 and a chromogenic substrate such as PN:T343. The detection limit for Human EMAP-II is 1 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used.
Other Applications Reported In Literature ?
IHC (NBF/Par.): This antibody should give satisfactory staining results when used at a concentration of 5-15 µg/ml. The recommended secondary antibody for IHC is PN:G505. For chromogenic detection with high signal and low background use PN:D100 or PN:K107.
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.
Goat Anti-Human Endothelial Monocyte Activating Polypeptide-II (EMAP-II) recognizes Human EMAP-II. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.
Endothelial monocyte activating polypeptide II (EMAP II) is a pro-inflammatory cytokine with anti-angiogenic properties. This protein was discovered in the supernatant of Meth-A fibrosarcoma cells and was shown to enhance the induction of the procoagulant Tissue Factor (TF) on endothelial cells. Besides up-regulation of TF mRNA, EMAP II increases cellular receptors for TNF on endothelial cells, which is likely to enhance the predisposition of tumors to undergo thrombosis and hemorrhagic necrosis, once challenged with TNF.1 EMAP II functions as a potent inhibitor of primary and metastatic tumor growth, has strong inhibitory effects on endothelial cells and can reduce intratumoral expression of the angiogenesis inducer vascular endothelial growth factor (VEGF). 2 It is also chemotactic towards neutrophils and monocytes and induces myeloperoxidase activity from neutrophils.
