Scientific Data Images for Human Complement Component C9 Antibody (887025)

Detection of Human Complement Component C9 antibody by Western Blot.

Detection of Human Complement Component C9 by Western Blot.

Western blot shows human plasma. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Complement Component C9 Monoclonal Antibody (Catalog # MAB8126) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Complement Component C9 at approximately 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human Complement Component C9 antibody by Simple WesternTM.

Detection of Human Complement Component C9 by Simple WesternTM.

Simple Western lane view shows human plasma, loaded at 0.5 mg/mL. A specific band was detected for Complement Component C9 at approximately 78 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human Complement Component C9 Monoclonal Antibody (Catalog # MAB8126). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Pathogenicity and effect of variants on protein function(A) Representation of the structure of MAC and C8 complex. The schematic representation of MAC shows the location of the identified variants in protein complex. 3D visualization of C8 complex showing the three subunits (C8 alpha  – green, C8 beta  – teal, C8 gamma  – magenta). Variants are indicated by red residues, and WT residues are in yellow. Potential hydrogen bonds formed by residues are indicated by dashed yellow lines. Hydrogen bonds gained by introduction of variants are marked by white arrows, and hydrogen bonds lost are marked by a dashed white ellipsoid.(B) Immunoblots showing expression of C8 and its direct partners within the membrane attack complex (MAC) in human retinal pigment epithelium (RPE) and lack of expression in HEK293 cells.(C) Co-IP analyses on the interaction between C8 alpha, beta, and gamma subunits in protein lysates from HEK293 cells.(D and E) Quantification of IP signal in lysates from HEK293 cells. Relative amounts of C8 subunits are plotted on a Jitter plot. Individual measurements are marked by a dot, and the quadrant range is indicated by a box. Transfection (repeated in triplicates) conditions are indicated by a “+” under each panel. Quantification of C8 alpha, beta, and gamma subunits is indicated in green, teal and magenta, respectively. Wilcoxon test was done to assess statistical significance, and comparison approaching significance are indicated.

Molecular mechanisms of MAC assembly in severe hypoxia-exposed MSCs. MSCs were exposed to hypoxia for 24 h. A C5b and C9 levels were analyzed using Western blot. beta actin was used for normalization of protein loading. The levels of both B C5b and C C9 increased significantly in hypoxic MSCs compared to MSCs under normoxia.

Background: Complement Component C9

Complement Component 9 (C9) is a 65-70 kDa protein of the complement membrane attack complex (C5b-9) that binds C5b-8, polymerizes, and forms pores upon activation of the complement cascade. Mature human C9 shares 60% and 66% amino acid sequence identity with mouse and rat C9, respectively. It may be proteolytically cleaved by thrombin into a 28-34 kDa cysteine-rich, mannosylated soluble C9a subunit, and a 37-38 kDa membrane-anchored N-glycosylated C9b. These fragments are also able to polymerize.

Alternate Names

    Thank you for reviewing our product. We are sorry to hear that this product did not perform as expected. We have been in touch with the customer to resolve this issue according to our Product Guarantee and to the customer’s satisfaction. The customer worked with our Technical Support team and had success detecting the complexed form of Complement Component C9 in the complement membrane attack complex (C5b-9) while using a polyclonal antibody for Human Complement Component C9 (AF8126). We have not tested complement membrane attack complex (C5b-9) detection with MAB8126 in-house.
