Catalog #APB0004-5Size: 5mlIntroductionAnti-Mouse Beads contains sepharose beads coated with goat anti-mouse IgG, for purification of mouseIgG class of antibodies or proteins with affinity to goat anti-mouse IgG. The goat anti-mouse IgG isaffinity purified and conjugated to the beads at 1-1.5 mg/ml ratio. This product can be used for 100-200times. For frequent use, an aliquot can be stored at 4ºC for 1 month with addition of 0.02% sodium azide(NaN3) to the storage buffer. It may also be used for immunoprecipitation (IP).Note: 20% ethanol was contained as protection solution in this product, please wipe off the ethanolbefore use.Anti-Mouse Beads SpecificationsMatrix: CNBr-activated SepharoseTM4FFBeads concentration: 1-1.5 mg/mlCoupling conditions of matrix: pH 7-9, 4°C to 25°C, 2-16 hBinding capacity: 4-7 mg IgG per mlBead size range: 45–165 μmMean bead size: 90 μmBead structure: Highly cross-linked agarose, 4%Max. flow rate: 4 ml/min/cm2Recommended flow rate: 1-3 ml/min/cm2Stability of the matrix: pH 3-11 (ligand dependent)Storage: Store at 4℃ for frequent use, at -20℃ for at least one year.
ProtocolA: Buffers preparation Equilibration buffer A: 1% Nacl+0.1% Na2HPO4, pH≈7.5 Equilibration buffer B: 1% CH3COONa adjusted pH to 5 by CH3COOH. Elution buffer: CH3COOH(pH =2~3) or 0.1mol Glycine Hydrochloride.. Wash buffer: 1% Nacl+0.1% Na2HPO4, pH≈7.5 Storage buffer: 30% glycerolB. Sample preparation1. Dilute the serum with equilibration buffer A to ensure its content and pH closed to equilibration bufferA.2. Centrifuge diluted serum supernatants to sediment debris.3. Filter supernatants through 0.45μm filter.C. Affinity-purification1. Load the Anti-mouse beads into the empty column.2. Wash column with Wash buffer in 3-5 column volumes to remove the glycerol, and then, equilibratecolumn by washing with Equilibration buffer A in 5-10 column volumes.3. Bring the sample to room temperature, and load it into the column by a syringe or a pump. The totalvolume of the sample applied is not critical in most cases.4. Load the sample into the column and collect the flow liquid, repeat this action for 3-5 times. Ifnecessary, repeat for more times, then deal with the collected liquid reasonably.5. Wash the column with Equilibration buffer B to remove other proteins.6. Elute with Elution buffer, collect the flow liquid (antibody), adjust its pH by saturated Na2CO3 duringcollection. Then, customers can test the related data of the antibody as their own requirements.D. Re-equilibration and Storage1. Add 5-10ml Elution buffer to column to elute thoroughly, then neutralizate the column withEquilibration buffer A.2. Wash the column bed with Storage buffer in 3-5 column volumes, seal the bottom of the column andstore at -20℃ for at least one year. For frequent use, an aliquot can be stored at 4ºC for 1 month withaddition of 0.02% sodium azide (NaN3) to the storage buffer.
