Recombinant Human His6-ATG7 Isoform 1 Protein, CF Summary

Product Specifications

>90%, by SDS-PAGE under reducing conditions and visualized by Colloidal Coomassie® Blue stain
Recombinant Human His6-ATG7 (Apg7) is a member of the Apg-activating (E1) enzyme family that is required for the first step of the enzymatic cascade that subsequently utilizes a Apg-conjugating (E2) enzyme and a Apg ligase (E3) to conjugate Apg to substrate proteins. Reaction conditions will need to be optimized for each specific application. We recommend an initial Recombinant Human His6-ATG7 (Apg7) concentration of 50-200 nM.
Spodoptera frugiperda, Sf 21 (baculovirus)-derived human ATG7 protein
Contains an N-terminal 6-His tag
Accession #
Predicted Molecular Mass
80 kDa

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: ATG7

ATG7, also known as APG7, is a 78 kDa cytosolic ubiquitin­E1-­like enzyme that plays a key role in the autophagy pathway of intracellular bulk degradation.  It is required for the conjugation of ATG5 to ATG12, the lipidation of ATG8 proteins including GABARAP, GABARAPL1, GABARAPL2 or MAP1LC3A, and the subsequent formation of autophagosomes.  ATG7 is required for mitochondrial removal during erythropoiesis (“mitophagy”) and for the maintenance of axonal homeostasis.  Alternate splicing of human ATG7 generates an isoform that lacks 31 aa at the C-­terminus, a region that is required for ATG8 lipidation. Human ATG7 shares 93% aa sequence identitiy with mouse and rat ATG7.  This recombinant proteins has an N-terminal 6-His tag.
