TGFB1 CTS™ Recombinant Human Protein (Gibco™)

Cell Therapy Systems CTS™ Recombinant Human TGF beta 1 (TGFB1) is a bioactive protein intended for use in cell culture applications, including pre-clinical and clinical cell therapy studies. TGFB1 acts synergistically with TGF-α in inducing transformation and acts as a negative autocrine growth factor. Dysregulation of TGFB1 activation and signaling may result in apoptosis. The lyophilized TGFB1 CTS™ Recombinant Human is verified for activity through dose-dependent inhibition of proliferation of mouse HT-2 cells stimulated with mouse IL-4.

The GIBCO® CTS™ product line enables you to reduce your burden in qualifying reagents during your transition from research applications to clinical applications.

High Purity
To help verify that GIBCO® CTS™ Recombinant growth factors are of the highest quality, each protein is analyzed for purity, along with structural homogeneity, to help ensure a biologically active protein. The purity of each GIBCO® CTS™ recombinant growth factor is verified by SDS-PAGE to be over 95% pure and to have endotoxin levels below 0.1 ng/μg.

High Biological Activity
All GIBCO® CTS™ Recombinant growth factors are verified for activity. Each lot has its own ED50 determined using an activity assay based on a specific function of the growth factor. The activity of our TGFB1 CTS™ Recombinant Human growth factor is determined by the dose-dependent inhibition of proliferation of mouse HT-2 cells stimulated with mouse IL-4 to have an ED50 ≤0.2ng/mL. Optimal concentration for individual applications should be determined by a dose response assay.

TGF-B1 Mouse ProcartaPlex™ Simplex Kit (Invitrogen™)

The Mouse TGF-B1 Simplex ProcartaPlex kit measures TGF-B1 protein and is designed to be combinable with other Simplex kits so that you can create your own multiplex panel that utilizes Luminex xMAP technology for protein detection/quantitation. When combining multiple Simplex kits (i.e., when you are not using a pre-configured Multiplex Panel), only one buffer kit (sold separately) is needed for each assay plate regardless of plex size.

ProcartaPlex immunoassays are based on the principles of a sandwich ELISA, using two highly specific antibodies binding to different epitopes of one protein to quantitate up to 80 protein targets simultaneously when using the FLEXMAP 3D or Luminex 200 instrument and up to 50 protein targets when using the MAGPIX instrument. ProcartaPlex assays require as little as 25 µL of plasma or serum, or 50 µL of cell culture supernatant, and just four hours to obtain analyzed results.

Flexible panels—design your own panels with Simplex kits to measure your own array of targets
More results per sample—measure up to 80 protein targets in a single 25–50 µL sample
Well-established Luminex technology—the most referenced multiplexing platform for protein detection and quantitation

The Luminex MagPlex superparamagnetic microsphere beads in the ProcartaPlex assay are internally dyed with precise proportions of red and infrared fluorophores to create 100 spectrally unique signatures that can be identified by the Luminex xMAP detec¬tion systems (Luminex 200, FLEXMAP 3D, and MAGPIX systems). Similar to a sandwich ELISA, the ProcartaPlex assay uses matched antibody pairs to identify the protein of interest. In a ProcartaPlex multiplex assay, each spectrally unique bead is labeled with antibodies specific for a single target protein, and bound proteins are identified with biotinylated antibodies and streptavidin–R-phycoerythrin (RPE). The conjugation of protein-specific antibodies to a distinct bead allows for analysis of multiple targets in a single well.

The most significant difference between a ProcartaPlex assay and ELISA is that the capture antibody in the ProcartaPlex assay is conjugated to a magnetic bead and not adsorbed to the microplate well, so the ProcartaPlex assay reagents are free-floating in the solution. For detection, the Luminex 200 instrument, for example, contains two lasers, one to distinguish the spectral signature of each bead and the second to quantify the amount of RPE fluorescence, which is proportional to the amount of protein present in the sample. ProcartaPlex multiplex assays can profile up to 80 times more target proteins using significantly less sample in the same time that it takes to perform a traditional sandwich ELISA.

ProcartaPlex Simplex kits provide the ability to create your own unique panel . More than 90% of ProcartaPlex Simplex targets can be combined, providing you with superior flexibility when creating your own multiplex panel.

ProcartaPlex Simplex kits are available across six species (human, mouse, rat, nonhuman primate, porcine, and canine). Visit thermofisher.com/procartaplex for more information, including a comprehensive list of individual protein targets.

LanthaScreen™ PDCD4 HEK 293E Cell Line

The PI3K⁄AKT⁄mTOR pathway mediates signals for cell growth and survival, transcription and translation, and regulated cell death. The significance of mTOR has been underscored recently by the identification of two distinct cellular complexes: mTORC1 (includes raptor and is rapamycin sensitive) and mTORC2 (includes rictor and is insensitive to rapamycin). Activation of the pathway by insulin (or other mitogens) leads to the phosphorylation of programmed cell death protein 4 (PDCD4) via mTORC1 (indirectly through the ribosomal protein p70 S6 kinase). LanthaScreen® PDCD4 HEK293E is a human cell line which constitutively expresses GFP-PDCD4 fusion proteins. This kinase target was introduced using lipid transfection followed by selection with Blasticidin. These cells are a clonal population isolated by FACS using GFP fluorescence as a sorting marker. A homogenous immunoassay ("addition only", no wash steps) was developed in 384-well format using a TR FRET-based detection method to monitor the phosphorylation of Ser457 on GFP-PDCD4 using a terbium-labeled phosphospecific antibody. The assay has been optimized for performance under numerous experimental conditions (e.g., cell plating density, DMSO tolerance, insulin stimulation time, etc.) and displays excellent statistical data (Z' > 0.6). Moreover, this cell line has been validated with different stimuli and known inhibitors (shows correct EC50 and IC50 values) and serves as robust cellular readout for mTORC1 signaling.
