Description
The AF3-12.1 antibody specifically recognizes the H-2K[k] MHC class I alloantigen. Reactivity with other haplotypes (e.g., b, d, f, j, p, q, r, s, u, v) has not been observed.
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.

Specifications

General

SourceMouse KGF, amino acids Cys32-Thr194 (Accession# BC052847.1), was expressed in E. coli.
Molecular MassThe 163 amino acid recombinant protein has a predicted molecular mass of approximately 18.7 kD. The protein migrates at approximately 21 kD in DTT-reducing conditions and non-reducing conditions by SDS-PAGE. The predicted N-terminal amino acid is Cys.
Purity>95%, as determined by Coomassie stained SDS-PAGE.
FormulationSterile-filtered with 0.2 µm filter, solution is comprised of 10 mM MOPS, 50 mM Na2SO4, 0.5 mM EDTA, and 0.5 mM DTT in 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.
ActivityThe ED50 is 0.1 - 0.5 ng/ml, corresponding to a specific activity of 0.2 - 1 x 107 units/mg, as determined by a dose-dependent MCF-7 cell proliferation in the presence of 10 µg/ml heparin. The proliferation was measured by the colorimetric MTS assay.
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].
