S-arrestin Overexpression Lysate Summary

• Description:

  S-arrestin Transient Overexpression Lysate

  
  Expression Host: HEK293T
  
  Plasmid: RC220057
  
  Accession#: NM_000541
  
  Protein Tag: C-MYC/DDK
  
  You will receive 1 vial of lysate (100ug) and 1 vial of empty vector negative control (100ug). Each vial of cell lysate contains 100ug of total protein (at 1 mg/ml).
• Gene: SAG

Applications/Dilutions

• Dilutions:
  • Western Blot
• Application Notes: This product is intended for use as a positive control in Western Blot. Overexpression of the target protein was confirmed using an antibody to DDK (FLAG) epitope tag (NBP1-71705) present on the protein construct.
  
  Each vial of cell lysate contains 100ug of total protein which should be sufficient for 20-50 reactions. Depending on over-expression level, antibody affinity and detection system, some lysates can go as low as 0.1 ug per load. We recommend starting with 5ug of cell lysate.
• Theoretical MW: 44.9 kDa.
  Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Packaging, Storage & Formulations

• Storage: Store at -80C. Avoid freeze-thaw cycles.
• Buffer: RIPA buffer

Lysate Details for Array

• Type: Overexpression

Notes

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

Alternate Names for S-arrestin Overexpression Lysate

• arrestin 1
• RP47,48 kDa protein
• S-antigen; retina and pineal gland (arrestin)
• S-arrestin
• visual arrestin

Background

Members of arrestin/beta-arrestin protein family are thought to participate in agonist-mediated desensitization of G-protein-coupled receptors and cause specific dampening of cellular responses to stimuli such as hormones, neurotransmitters, or sensory signals. S-arrestin, also known as S-antigen, is a major soluble photoreceptor protein that is involved in desensitization of the photoactivated transduction cascade. It is expressed in the retina and the pineal gland and inhibits coupling of rhodopsin to transducin in vitro. Additionally, S-arrestin is highly antigenic, and is capable of inducing experimental autoimmune uveoretinitis. Mutations in this gene have been associated with Oguchi disease, a rare autosomal recessive form of night blindness. (provided by RefSeq)
