Anti-PI3 Kinase Antibody, p85, N-SH3, clone AB6

产品说明

一般描述

The enzyme phosphatidylinositol 3 kinase (PI3 kinase) is a lipid kinase that is thought to phosphorylate second messengers in growth signaling pathways. PI3K exists as a heterodimer of catalytic 110 kDa (p110) and regulatory 85 kDa (p85, p50 or p55) subunits. The p85 unit consists of two closely related proteins: p85 alpha, which binds tightly to the catalytic subunit and p85 beta, a protein of unknown function. They share 62% amino acid sequence identity. p85 alpha lacks PI3 kinase activity, but may serve as regulator of the catalytic subunit, p110, by acting as the link between PI3K and the ligand activated receptor. Both isoforms bind to activated receptors and serve as tyrosine kinase substrates.

特异性

This antibody recognizes p85 alpha subunit of PI3 Kinase; does not recognize p85 beta subunit.

免疫原

Immunocytochemistry:
10 µg/mL of a previous lot of this antibody was used in immunocytochemistry.
Immunoprecipitation:
4 µg of a previous lot immunoprecipitated PI3 Kinase from 500 µg of an A431 RIPA lysate, as confirmed by immunoblot using a polyclonal PI3 Kinase antibody (Catalog # 06-195).

质量

Routinely evaluated by Western Blot on RIPA lysates from human A431 cells, or RIPA lysates from rat L6 myoblasts.
Western Blot Analysis:
0.5-2 µg/mL of this lot detected PI3 Kinase in RIPA lysates from human A431 cells; previous lots detected PI3 Kinase in RIPA lysates from rat L6 myoblasts.

外形

Protein A chromatography
Format: Purified
Purified mouse monoclonal IgG1κ in buffer containing PBS, pH 7.2 with 50% glycerol.

储存及稳定性

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations:
Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20ºC. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20ºC may cause glycerol-containing solutions to become frozen during storage.

分析说明

Control
NIH-3T3 cell lysate, A431, MCF7 or Raji cells lysate, HeLa cells, breast carcinoma.
Included Positive Antigen Control: Catalog # 12-301, non-stimulated A431 cell lysate. Add 2.5 µL of 2-mercaptoethanol/100 µL of lysate and boil for 5 minutes to reduce the preparation. Load 20 µg of reduced lysate per lane for minigels.
