1x Ab-conjugated beads (S4P8 - TGFβ1 ab-bead). PN: B111206A. One vial containing 5 mL of anti-TGFβ1 conjugated to AimPlex Bead S4P8.
2x Biotin-detection Ab (TGFβ1 Biotin-dAb). PN: B111206B. One vial containing 1.5 mL of biotinylated anti- TGFβ1.
2x TGFβ dAb Diluent. PN: 07TDX21. One vial containing 1.5 mL of biotin detection antibody diluent
Lyophilized Standard Mix - TGFβ1. PN: UTGFB1AG. One vial containing lyophilized recombinant TGFβ1.
Application: Optimal antibody pair and antigen standard for assaying Human, mouse, rat, porcine, canine and non-human primate (NHP) TGFβ1. To be used in conjunction with the AimPlex Basic Kit for Premixed Panels (PN: U100005) and the TGFβ Diluent Kit (PN: P900110, universal for all sample types). Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.
NOTE: Samples should be pretreated with HCl then neutralized to activate latent TGFβ1 to the immunoreactive form for accurate measurement. Do not pretreat the TGFβ1 Standard. Add 20 µL of 1N HCl to 100 µL of sample. Incubate for 10 minutes at room temperature after mixing. Neutralize with an addition of 20 µL of 1.2N NaOH/0.5M HEPES. The activated samples may need to be diluted with 1x TGFbeta Assay Buffer for the assay. The appropriate dilution factor should be determined by the investigator according to the sample type and experimental conditions. Because of the sample pretreatment, the TGFβ1 assay cannot be multiplexed with any other AimPlex assays.
Storage: 2-8 C in the dark.
Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Transforming growth factor beta 1 (TGF-β1) or TGFB is a polypeptide member of the transforming growth factor beta superfamily of cytokines. It is a secreted protein that performs many cellular functions, including the control of cell growth, cell proliferation, cell differentiation and apoptosis. In humans, TGF-β1 is encoded by the TGFB1 gene. TGF-β is a multifunctional set of peptides that controls proliferation, differentiation, and other functions in many cell types. TGF-β acts synergistically with TGFA in inducing transformation. It also acts as a negative autocrine growth factor. Dysregulation of TGF-β activation and signaling may result in apoptosis. Many cells synthesize TGF-β and almost all of them have specific receptors for this peptide. TGF-β1, TGF-β2, and TGF-β3 all function through the same receptor signaling systems. TGF-β1 plays an important role in controlling the immune system, and shows different activities on different types of cell, or cells at different developmental stages. Most immune cells (or leukocytes) secrete TGF-β1. Diseases associated with TGF-β1 include camurati-engelmann disease and kidney hypertrophy.
