製品の概要
Contents:
Supplied as a 50% slurry in 20% Ethanol.
Features:
High binding capacity = Binding of IgG ≥16 mg human or rabbit IgG/mL Protein A-Sepharose®.
Minimal leaching of the ligand
Flow Rate Tested* = 2.07 mL/min.
*Test condition: = Calculations based on the time required to pass 18 mL of water through 2 mL settled beads (column diameter 1.5 cm).
Usage = Reusable for up to 10 times without significant loss of binding capacity.
Store beads at 4°C.
The beads may be damaged above 40°C.
DO NOT FREEZE.
Wash beads 3 times with 3x bead volume of desired buffer before use.
Applications:
- Purification of monoclonal and polyclonal antibodies from culture media, serum, ascites fluid or hybridoma supernatants.
- Isolation of antibody/antigen complexes in immunoprecipitation experiments, since only the Fc region is involved in antibody binding and the Fab region is available for binding antigen.

特記事項
This product is manufactured by BioVision, an Abcam company and was previously called 6501 Protein A Sepharose. 6501-5 is the same size as the 5 ml size of ab193256.
Protein A Sepharose® beads are prepared by covalently coupling recombinant Protein A to 6% cross-linked Sepharose® beads. Protein A is a genetically engineered protein containing five IgG-binding regions of native Protein A. The cell wall binding region, albumin binding region and other non-specific regions have been eliminated from the recombinant Protein A to ensure maximum specific IgG binding. The coupling technique is optimized to give a higher binding capacity for IgG and minimum leaching of recombinant Protein A. The IgG binding capacity of Protein A Sepharose® is ≥ 16 mg human or rabbit IgG per mL of wet beads. Protein A Sepharose® beads display high chemical and physical stability as well as high flow rate, hydrophilicity and high gel strength. This product can be used for IgG purification and immunoprecipitation.

Overexpression of TTLL4 in MDA-MB231 cells increases MT-glutamylation.b Polyglutamylated proteins were immunoprecipitated from control and TTLL4 plus cells, using an antibody against polyglutamylation modification (GT335). Cell lysates ("input"), supernatants ("S/N") from cell lysates incubated with GT335-coupled beads and proteins bound to GT335 coupled beads ("beads") were analyzed
by Western blotting for β-tubulin and NAP-1 levels. IgG signals served as loading control. The lower band appearing in the NAP-1 blot is a residue signal of ?-tubulin antibody because the same membrane was used to probe against all 3 proteins. -

Resistin was immunoprecipitated from OB ACM using resistin antibody-agarose bead conjugates (OB ACM - resistin IP). IgG isotype antibody control-agarose bead conjugates were used on the same samples as a control (OB ACM).(A) Resistin protein is detected by immunoblotting of resistin-antibody lysates but not IgG control lysates following immunopreciptation.
