Human Plasma Fibronectin Purified Protein, ยี่ห้อ Sigma

DESCRIPTION

General description

Product Source: Human donor plasma.

Human fibronectin (HFN) is suitable for use as an attachment factor in the propagation of cells in vitro when used to coat cell culture surfaces, including plastic ware, glassware, and microcarrier beads.

Packaging

10 mg in 10 x 1 mg

5 mg in 5 x 1 mg

Application

Immunochemical standard

Cell attachment and proliferation assays on human endothelial cells, human keratinocytes and human dermal fibroblasts

Suggested Procedure for Coating Cell Cultureware

1.Determine the amount of HFN needed to coat culture vessels by multiplying the total surface area (cm2) by the desired concentration (μg/mL) of HFN. Recommended amount is 2-10 μg/cm2.

2.Wet the surface of each culture vessel to be coated with a minimum amount of sterile balanced salt solution (serum and protein free) required to cover the entire area.

3.Introduce the proper CO2 atmosphere, if required.

4.Add the calculated amount of HFN to each culture vessel.

5.Allow HFN to adsorb to the surface of the vessel for 5-20 minutes.

6.Remove residual balanced salt solution before proceeding with standard cell culture procedures

Physical form

Liquid in 150 mM NaCl, 10 mM sodium phosphate, pH 7.5, sterile filtered, containing no preservatives.

Storage and Stability

Maintain at 2-8°C for up to 6 months from date of receipt. Do not freeze.

Analysis Note

A double band of 220 kDa is present under reduced conditions.hFN is purified by affinity chromatography on gelatin agarose, followed by chromatography on heparin-agarose.Plasma from donors has been screened, and shown to be negative for HIV, HTLV, Hepatitis B and C.
