Fc gamma RIIB/CD32b Overexpression Lysate Summary

Description

Fc gamma RIIB/CD32b Transient Overexpression Lysate


Expression Host: HEK293T

Plasmid: RC211982

Accession#: NM_004001

Protein Tag: C-MYC/DDK

You will receive 1 vial of lysate (100ug), 1 vial of empty vector negative control (100ug), and 1 vial of 2xSDS sample buffer (250ul). Each vial of cell lysate contains 100ug of total protein (at 1 mg/ml). The 2xSDS Sample Buffer consists of 4% SDS, 125mM Tris-HCl pH6.8, 10% Glycerol, 0.002% Bromophenol blue, 100mM DTT.

Applications/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. Add an equal amount of cell lysate and 2X SDS Sample buffer and boil the SDS samples for 10 minutes before loading.
Theoretical MW
33.9 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.

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.

Background

Low affinity IgG Fc receptor gamma II (Fc-gamma II), also known as CD32, is a member of the immunoreceptor tyrosine-based activating/inhibitory motif (ITAM/ITIM) family. Fc gamma receptors play a critical role in immunity by linking the IgG antibody mediated response with the regulatory functions of the immune system (1). Three classes of Fc gamma receptor exist; Fc gamma RI (CD64, a high affinity receptor), Fc gamma RII, and RIII (CD32 and CD16 respectively, both low affinity receptors). Fc gamma RIIa is an activating receptor, while RIIb1, RIIb2, and RIIb3 are inhibitory receptors generated by alternative splicing (1-2). Fc gamma RIIa is critical for antigen-presenting-cell activation and Fc gamma RIIb downregulates B-cell functions (3). Fc gamma RIIb has also been known to block the inflammatory immune response in mice (4). Once phosphorylated on tyrosine residues, Fc gamma RIIb associates with SHIP to downregulate phagocytosis.
