K-562 Pervanadate Cell Lysate Summary

• Description: K562 Pervanadate Unstimulated Control Lysate
• Preparation Method: Tissue specimens are homogenized in modified RIPA buffer to obtain the soluble proteins, and centrifuged to clarify. The pellet was further extracted with a second buffer to obtain the less soluble protein fraction. The lysate solution may appear turbid at cold temperatures due to insolubility of buffer components. The solution should clear upon warming to room temperature.

Applications/Dilutions

• Dilutions:
  • SDS-Page
  • Western Blot 20ul/Lane
• Application Notes: Western blot membranes were incubated with diluted antibody in 5% non-fat milk, PBS, 0.04% Tween20 for 1hour at room temperature.
  Confluent cultures of K-562 cells were serum starved for 2 hours. Cells were then either left untreated or treated with pervanadate (1 mM) for 30 minutes at 37 degrees C. Cells were lysed in 1% SDS, 1.0 mM sodium ortho-vanadate, 10 mM Tris (pH 7.4) buffer. Protein concentration was determined using the BCA method before diluting to final concentration and buffer.

Packaging, Storage & Formulations

• Storage: Aliquot and store at -20C or -80C. Avoid freeze-thaw cycles.
• Buffer: In electrophoresis sample buffer (62.5 mM Tris pH 6.8, 2% SDS, 5% glycerol, 0.003% bromophenol blue, 0.9% Beta-mercaptoethanol).
• Concentration: 1 mg/ml

Lysate Details for Array

• Type: Cell
• Tissue Condition: Chronic Myelogenous Leukemia

Background

K-562 lysate was derived from a human chronic myelogenous leukemia (CML) cell line. Pervanadate is a protein tyrosine phosphatase inhibitor that is commonly used to increase tyrosine phosphorylation in cells. When cells are treated with pervanadate for 30 minutes they undergo significant tyrosine phosphorylation.
