Purity of recombinant human IL-6 was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue

Recombinant human IL-6 (HZ-1019) stimulates dose-dependent proliferation of the 3G12B10 hybridoma cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. 3G12B10 cells were treated with increasing concentrations of recombinant IL-6 for 96 hours. The EC50 range is 0.03-0.24 ng/mL​.
 

Recombinant human IL-6 (HZ-1019) stimulates dose-dependent proliferation of the 7TD1 hybridoma cell line. Cell number was quantitatively assessed by CellTiter® Cell Viability Reagent. 7TD1 cells were treated with increasing concentrations of recombinant IL-6 for 96 hours. The EC50 is <0.5 ng/mL​.

GMP Recombinant human IL-6 (HZ-1019-GMP) stimulates dose-dependent proliferation of the 3G12B10 hybridoma cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. 3G12B10 cells were treated with increasing concentrations of GMP recombinant IL-6 for 96 hours. The EC50 was determined using a 4-parameter non-linear regression model. Activity determination was conducted in triplicate on a validated bioassay. The EC50 range is 0.03-0.24 ng/mL​.

Untreated HUVEC cells, HUVEC cells (treated with 0.5 µg/ml LPS for 24 hours, then add 300 ng/ml protein transport inhibitor last 20 hours) were subjected to SDS PAGE followed by western blot with 21865-1-AP (IL-6 antibody) at dilution of 1:1000 incubated at room temperature for 1.5 hours.

IP result of anti-IL-6 (IP:21865-1-AP, 4ug; Detection:21865-1-AP 1:1000) with LPS and Protein transport inhibitor treated HUVEC cells lysate 800 ug.

Immunofluorescent analysis of (-20°C Methanol) fixed LPS and Brefeldin A treated HUVEC cells using IL-6 antibody (21865-1-AP) at dilution of 1:400 and CoraLite®488-Conjugated AffiniPure Goat Anti-Rabbit IgG(H+L) (SA00013-2).

untreated, LPS and Brefeldin A treated RAW 264.7 cells were subjected to SDS PAGE followed by western blot with 26404-1-AP (IL-6 antibody) at dilution of 1:600 incubated at room temperature for 1.5 hours.

Recombinant human IL-6 (Cat.NO. HZ-1019) stimulates proliferation of hybridoma (Proteintech mouse anti-GST clone 3G12B10) in a dose-dependent manner (blue curve, refer to bottom X-left Y axis). The activity of human IL-6 (1 ng/mL HZ-1019) is neutralized by mouse anti-human IL-6 monoclonal antibody 69001-1-Ig at serial dose (red curve, refer to top X-right Y axis). The ND50 is typically 10-30 ng/mL. The NeutraControl mouse anti-human IL-6 monoclonal antibody 69501-1-Ig could recognize human IL-6 but could not neutralize human IL-6 activity in the range of 0.06 ng/mL-1000 ng/mL (green curve, refer to top X-right Y axis).

Indirect ELISA was carried out by coating recombinant Human IL-6 (Cat.NO. HZ-1019) at 70 ng/well followed by blocking and adding serial diluted IL-6 antibody 69001-1-Ig and 69501-1-Ig respectively. Signal was developed with TMB and stopped by H2SO4. Signal strength was measured by absorbance at 450 nm.

LPS and Brefeldin A treated NR8383 cells were subjected to SDS PAGE followed by western blot with 30953-1-AP (IL-6 antibody) at dilution of 1:500 incubated at room temperature for 1.5 hours.

LPS and Brefeldin A treated RAW 264.7 cells were subjected to SDS PAGE followed by western blot with 29444-1-AP (IL-6 antibody) at dilution of 1:1000 incubated at room temperature for 1.5 hours.

LPS and Brefeldin A treated HUVEC cells were subjected to SDS PAGE followed by western blot with 83747-7-RR (IL-6 antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 83747-7-PBS in a different storage buffer formulation.

Biolayer interferometry (BLl) kinetic assays of 83747-7-RR against Human IL-6 were performed. The affinity constant is 1.72 nM.
