Recombinant Mouse SMOC-1 Protein, CF Summary

Product Specifications

Purity
>95%, by SDS-PAGE under reducing conditions and visualized by silver stain
Endotoxin Level
<0.01 EU per 1 μg of the protein by the LAL method.
Activity
Measured by the ability of the immobilized protein to support the adhesion of A431 human epithelial carcinoma cells.

When 5 x 104 cells/well are added to rmSMOC-1 coated plates, cell adhesion is enhanced in a dose dependent manner after 75 minutes at 37 °C. The ED50 for this effect is 1-4 μg/mL.

His26-Val452, with a C-terminal 6-His tag
Accession #
N-terminal Sequence
Analysis
His26 & Ile35
Predicted Molecular Mass
47.9 kDa
SDS-PAGE
60-65 kDa, reducing conditions

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: SMOC-1

SMOC-1 (secreted, or SPARC-related, modular calcium-binding protein 1) is a 70 - 90 kDa secreted glycoprotein that is a member of the SPARC family of matricellular molecules (1). Mature mouse SMOC-1 is 427 amino acids (aa) in length. It contains one Kazal-like domain (aa 42 - 86), two thyroglobulin type-1 segments (aa 91 - 157 and223 - 291) and two functional EF-hand sequences (aa 358 - 393 and 395 - 430) (1, 2). Two splice variants contain an insertion of eleven aa after Lys174, with one of these also including an alternate start site at Met65 (3). Mature mouse SMOC-1 shares 99% aa identity with rat SMOC-1 and 92% aa identity with human, canine and bovine SMOC-1. The principal difference between rodents and other mammals is an additional 19 aa near the C-terminus of rodent SMOC-1. Like other matricellular proteins, SMOC-1 is primarily expressed in basement membranes, although it has also been found in other extracellular matrices and the oocyte zona pellucida (1). It is present early in mouse embryogenesis, and is produced by cells deriving from all three germ layers (4). Recombinant bacterially produced human SMOC-1 and SMOC-2 were both shown to bind the acute phase protein, C-reactive protein, and the adhesion proteins, fibulin and vitronectin (2). A signaling role for SMOC-1 was shown in rat mesangial cells: induction of nitric oxide in response to inflammatory cytokines downregulates SMOC-1 which, in turn, downregulates expression of TGF-beta and TGF-beta -regulated genes. This mechanism is proposed to limit the profibrotic effects of TGF-beta, for example in the glomerulus (5). In Xenopus, the SMOC paralog has been shown to antagonize BMP activity.
