Immunohistochemical analysis of paraffin-embedded human liver cancer tissue slide using 20215-1-AP (IGF1B-Specific antibody) at dilution of 1:200 (under 10x lens. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0).

Immunohistochemical analysis of paraffin-embedded human liver cancer tissue slide using 20215-1-AP (IGF1B-Specific antibody) at dilution of 1:200 (under 40x lens. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0).

Purity of recombinant human IGF-I 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 IGF-I (Cat no: HZ-1322) stimulates dose-dependent proliferation of the MCF-7 human breast cancer cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. MCF-7 cells were treated with increasing concentrations of recombinant IGF-I for 96 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 2-14 ng/mL.

Proteintech IGF-I (Cat no: HZ-1322) demonstrates equivalent fold induction and a 2-fold decrease in EC50 compared to leading competitors. Recombinant human IGF-I stimulates dose-dependent proliferation of the MCF-7 human breast cancer cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. MCF-7 cells were treated with increasing concentrations of recombinant IGF-I for 96 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 2-14 ng/mL.

Purity of recombinant human IL-12 beta 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.

GMP recombinant human IGF-I (Cat no: HZ-1322-GMP) stimulates dose-dependent proliferation of the MCF-7 human breast cancer cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. MCF-7 cells were treated with increasing concentrations of recombinant IGF-I 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 2-14 ng/mL.
