Description
The ME-9F1 monoclonal antibody specifically binds to mouse CD146. The CD146 adhesion molecule is a type 1 transmembrane glycoprotein and member of the immunoglobulin superfamily. CD146 is expressed by blood vessel endothelial cells and may play roles in forming intercellular junctions between endothelial cells and influencing the transendothelial migration of other cell types. CD146 is also expressed by some melanoma cell lines, NK cells and neutrophils. CD146 is not detectable on mouse monocytes, dendritic cells, T cells, NKT cells, B cells and smooth muscle cells. Increased expression of CD146 is reportedly associated with NK cell maturation and may be used to characterize different functional NK cell subsets. Activated CD146-positive mouse NK cells reportedly are less cytotoxic and secrete less IFN-γ than their CD146-negative counterparts.
BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to BD CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD CompBead to ensure that BD CompBeads are appropriate for your specific cellular application.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody.
1. Researchers should determine the optimal concentration of this reagent for their individual applications.
2. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
3. An isotype control should be used at the same concentration as the antibody of interest.
4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Molecular MassThe 178 amino acid recombinant protein has a predicted molecular mass of approximately 18.9 kD. The DTT-reduced and non-reduced protein migrates at approximately at 23-26 kD by SDS-PAGE. The N-terminal amino acid is Val.
Purity>95%, as determined by Coomassie stained SDS-PAGE.
Formulation0.22 µm filtered protein solution is in PBS, pH 7.2.
Endotoxin LevelLess than 0.01 ng per µg cytokine as determined by the LAL method.
Concentration10 and 25 µg sizes are bottled at 200 µg/mL. 100 µg size and larger sizes are lot-specific and bottled at the concentration indicated on the vial. To obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.
Storage & HandlingUnopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week and stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
ActivityED50 = 0.05 - 0.25 ng/ml, corresponding to a specific activity of 4 - 20 x 106 units/mg, as determined by M-NFS-60 cell proliferation induced by mouse G-CSF in a dose dependent manner.
ApplicationBioassay
Application NotesBioLegend carrier-free recombinant proteins provided in liquid format are shipped on blue-ice. Our comparison testing data indicates that when handled and stored as recommended, the liquid format has equal or better stability and shelf-life compared to commercially available lyophilized proteins after reconstitution. Our liquid proteins are verified in-house to maintain activity after shipping on blue ice and are backed by our 100% satisfaction guarantee. If you have any concerns, contact us at [email protected].
StructureHomotrimer.
DistributionMonocytes, mesothelial cells, fibroblasts, endothelial cells, and neurons.
FunctionG-CSF acts on myeloid progenitor cells to stimulate survival, proliferation, and neutrophilic maturation. On mature neutrophils, it enhances survival, superoxide anion and alkaline phosphatase production, arachidonic acid release, and antibody dependent cellular cytotoxicity.
InteractionHematopoietic progenitor cells, neutrophilic granulocytes, monocytes, macrophages, osteo macrophages, platelets, endothelial cells, trophoblastic cells, myoblasts, cardiomyocytes, neurons, and some small cell lung carcinoma cell lines.
