Source
Optimized DNA sequence encoding mouse Interleukin-12 mature chain was over-expressed in CHo cells.
Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/ug (1EU/ug).
Biological Activity
The ED(50) determined by the dose-dependent stimulation of IFN-gamma production by murine splenocytes co-stimulated with IL-18 is <.1 ng/ml, corresponding to a specific activity of > x units/mg.
Method
Mouse T Cell Primary CulturesPeripheral lymph node cells were pooled from axillary, inguinal, brachial, and cervical lymph nodes (excluding mesenteric (mes)LN).
Where explicitly stated in the figure legends mesLN were collected.
After lymphoid organ disaggregation, cells were washed and resuspended in complete media (RPMI-1640, 5%FCS, 2 mM L-gln, 100 U/ml penicillin/streptomycin, and 2.5×10-5 M 2beta-ME.
Anti-CD3 (145-2C11, BD) at 0-1 ug/ml and anti-CD28 (37.51, BD) at 2 ug/ml mAb were coated on plates (1h, 37 degree C, in PBS) and washed twice.
In transient TCR stimulations, cells were moved from Ab-coated to fresh wells on d2.
aAPC were described previouslyFunctional assays with T cells of healthy donorscelltype'>T cell activation experiments using the system of celltype'>T cell stimulator cells were done as previously described 4/well) were co-cultured with 1×105 celltype'>T cells, and following 48 h of stimulation, cell culture supernatant was harvested for cytokine measurement and methyl-3[H]-thymidine was added to the cultures.Expression of membrane-bound anti-CD3 antibody fragments on the T cell stimulator cells was detected via DyLight-649-conjugated goat antibodies to mouse IgG-H+L specific.
Isolation of human T cells and monocytes and generation of immature and mature monocyte-derived DC was done as previously described 5 T cells/well were added and cultured for 48 h in the presence of soluble TIM-3 antibodies or isotype control antibodies (bothfinal concentration: 5 ug/ml) as previously described 5/well) were co-cultured with allogeneic immature or mature human DC at the indicated cell numbers for 5 days in presence of the indicated antibodies (final concentration 10 ug/ml).
To assess T cell proliferation methyl-3[H]-thymidine (final concentration: 0.025 mCi Elmer/New England Nuclear Corporation,,) was added for the last 18 hours of.<>Methyl-3[H]-thymidine uptake was measured as described
Molecular Function
Cytokine
Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Preparation and Storage
The lyophilized protein is stable for at least years from date of receipt at-20 degree C. Upon reconstitution, this cytokine can be stored in working aliquots at 2 degree -8 degree C for one month, or at-20 degree C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Product Notes

The Il12b il12b (Catalog #AAA14439) is an Active Protein produced from CHO cells (Note: Host protein expression may be lot-specific and can be subject to change during production, including bulk orders.) and is intended for research purposes only. The product is available for immediate purchase. The amino acid sequence is listed below: MCPQKLTISW FAIVLLVSPL MAMWELEKDV YVVEVDWTPD APGETVNLTC DTPEEDDITW TSDQRHGVIG SGKTLTITVK EFLDAGQYTC HKGGETLSHS HLLLHKKENG IWSTEILKNF KNKTFLKCEA PNYSGRFTCS WLVQRNMDLK FNIKSSSSSP DSRAVTCGMA SLSAEKVTLD QRDYEKYSVS CQEDVTCPTA EETLPIELAL EARQQNKYEN YSTSFFIRDI IKPDPPKNLQ MKPLKNSQVE VSWEYPDSWS TPHSYFSLKF FVRIQRKKEK MKETEEGCNQ KGAFLVEKTS TEVQCKGGNV CVQAQDRYYN SSCSKWACVP CRVRS. It is sometimes possible for the material contained within the vial of "Interleukin-12 p40, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
