Overview

  • Product name
    E. coli Positive Control (Escherichia coli ) Whole Cell Lysate
  • General notes

    This E.coli lysate contains a 41 kd recombinant protein expressing 12 commonly used Tags which are fused to the N-terminus of the protein in the order of:
    T7 HSV
    C-Myc
    VSV-g
    Glu-Glu
    V5
    E-tag
    FLAG (DDDDK)
    S-tag
    HA
    6x His

    GST

    Tag sequences: T7 = CMASMTGGQQMG
    HSV = QPELAPEDPEDC
    CMYC = EQKLISEEDLC
    VSV-g = YTDIEMNRLGK
    GluGlu = EYMPME
    V5 = GKPIPNPLLGLDST
    E-tag = GAPVPYPDPLEPR
    FLAG = DYKDDDDK
    HA = YPYDVPDYAC
    6xHIS = HHHHHH

     

    Excellent as a loading control for Western blotting. Lysate expresses 11 different epitope tags.

Properties

  • Background
    Escherichia coli is a gram negative bacillus that belongs to a larger group of Enterobacteriae - bacteria that inhabit the gastrointestinal tract. Although usually a harmless resident of the gut, some strains have the potential to cause serious problems, especially where there is an immature immune system or immunosuppression, or where the subtype of organism has acquired the ability to produce pathogenic toxins.

Applications

Our Abpromise guarantee covers the use of ab5395 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use at an assay dependent concentration.

Use 0.5 - 2.0 µl for 10 - 12% gels.

Hey,

Is the concentration of the tagged fusion protein known? If not, do you sell any myc-tagged fusion proteins where the concentration is known?

Thank you for contacting us.
We do not have an exact concentration for this material and do not have another lysate where the exact concentration of the myc-tagged protein is known.
I hope this information is helpful to you. Please do not hesit...
