    HEK293T

  • Organism

    Human

  • Mutation description

    Knockout achieved by using CRISPR/Cas9, 19 bp deletion in exon2.

  • Passage number

  • Knockout validation

    Sanger Sequencing, Western Blot (WB)

  • Reconstitution notes

    To use as WB control, resuspend the lyophilizate in 50 µL of LDS* Sample Buffer to have a final concentration of 2 mg/ml. For reducing conditions, we recommend a final concentration of 0.1 M DTT.

    *Usage of SDS sample buffer is not recommended with these lyophilized lysates.

  • Notes

    Lysate preparation: Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10). This means that the protein of interest is denatured. If you require a native form of the protein please use the live cell version - found here. Please refer to our lysis protocol for further details on how our lysates are prepared.

    User storage instructions: Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.

Target

  • Function

    Calcium-binding protein that interacts with newly synthesized glycoproteins in the endoplasmic reticulum. It may act in assisting protein assembly and/or in the retention within the ER of unassembled protein subunits. It seems to play a major role in the quality control apparatus of the ER by the retention of incorrectly folded proteins.

  • Sequence similarities

    Belongs to the calreticulin family.

  • Cellular localization

    Endoplasmic reticulum membrane. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
  • Information by UniProt
