Product specifications

Intended use

This ELISA Flex kit is intended for the quantification of human latent Transforming Growth Factor-β1 (TGF-β1) in solution. For research use only. Not for use in diagnostic procedures.

Serum/Plasma samples

Analysis of serum/plasma with this kit requires the use of ELISA diluent. The ELISA diluent blocks heterophilic antibodies from cross-linking the assay antibodies, thereby preventing false-positive read-outs. Heterophilic antibodies are commonly found in human serum/plasma and can also be present in serum/plasma from other species. The ELISA diluent has been validated using from healthy human blood donors. It should be used for dilution of standard, samples, and detection antibody.For quantification of latent TGF-β1 in blood, the use of plasma is recommended since serum contains high levels of latent TGF-β1 released from platelets during sample preparation. Plasma can be obtained using EDTA, citrate or heparin as anti-coagulants. To minimize the platelet content in the sample, an additional centrifugation of plasma at 10,000 x g for 10 minutes is recommended.

Quantification of latent TGF-β1 - no need for sample pre-treatment
TGF-β1 is secreted in a latent, biologically inactive form, non-covalently linked with a Latency Associated Protein (LAP). The monoclonal antibodies MT593 and MT517-biotin bind to the LAP entity of human latent TGF-β1. This enables direct quantification of latent TGF-β1 in ELISA with no need of sample pre-treatment.

ApplicationELISA
AnalyteTGF-β1 (Latent TGF-β1)
ReactivityHuman, Non-human primates
Specificity

This kit is based on a matched pair of mAbs specific for the Latency Associated Protein (LAP) of human latent TGF-β1.

Cross-reactivity

The ELISA does not detect human latent TGF-β2 or -β3 or bovine latent TGF-β1. The mAbs cross-react with latent TGF-β1 from non-human primates (NHP). For more information please check the Cross-reactivity guide section below.

Shipping and Storage

Shipping

Shipped at ambient temperature.

Storage

Store antibodies and enzyme conjugate at 4-8 °C upon receipt. The ELISA standard should be stored at -20 °C.

Shelf lifeAt least 18 months from date of receipt.
Standard range0.5-50 pM
Representative standard curve for human Latent TGF-β1 ELISA Flex kit using pNPP substrate.

The systems reactive with NHPs are either based on cross-reactive human kits or specifically developed monkey kits (NHP).

Cross-reactivity verification tests have been performed in ELISpot and/or ELISA by Mabtech and/or by others. Evaluations of assays with less solid evidence of cross-reactivity are shown as symbols within parentheses.

TGF-β1 (Latent TGF-β1)

Analyte description

Transforming growth factor β1 (TGF-β1) is secreted by many cells and controls functions such as cell growth, cell differentiation, proliferation, and apoptosis. The cytokine TGF-β1 is an important regulator of immune functions. Specifically for T cells, TGF-β1 promotes the differentiation of regulatory T cells, preventing IL-1- and IL-2-dependent proliferation of activated T cells, the activation of helper T cells, and cytotoxic T cells. TGF-β1 is secreted in a latent, biologically inactive form, non-covalently linked with a latency associated protein (LAP).
