Overview
Type I collagen is the most abundant collagen and is found in connective tissues including tendon, ligament, dermis and blood vessel. It is the major component and the primary determinant of tensile strength of the extracelluar matrix (ECM). It is widely used as a thin layer on tissue-culture surfaces to enhance the attachment and proliferation of a variety of cells including endothelial cells, fibroblasts, hepatocytes, epithelial cells etc. In addition, collagen I can self-assemble into a 3-D superamolecular gel in vitro, making it an ideal biological scaffold to promote more in vivo-like cellular morphology and function.

Data/Specifications
Description: Purified Mouse Collagen Type I (Atelocollagen) from mouse tail tendon
Form: Lyophilized, salt free, 1 mg/ vial
Sterility: Passed sterility test for bacteria and fungi
Source: Mouse tail tendons
Purity:Mouse collagen type I > 90% / Mouse collagen type III < 10%
Purification:Collagen was extracted from washed dissected tissue into diluted acetic acid after mild pepsin treatment. Collagen type I was purified by using differential salt precipitation.
Reconstitution: Dissolve in 20 mM acetic acid. Suspension should be shaken or stirred for several hours or overnight between 2-8 °C. Material is dissolved when it appears homogeneous, with no schlieren pattern (light refraction due to differing protein concentrations in the suspensions). Recommended concentration 1-5 mg/mL.
Storage: Collagen dissolved in acetic acid is stable at 4 °C for 1 month. Lyophilized collagen long term storage at -20 °C or lower.
Applications: Cell culture (coating or 3D gel)

加样缓冲液的主要作用是使PCR产物与其混合,
使DNA沉于加样孔的底部,防止DNA跑出来.
1mol/l Tirs-HCl(PH8.8) 0.6ml
10%SDS 2ml
50%甘油 5ml
2-巯基乙醇 0.5ml
1%溴酚兰 1ml
水 0.9ml
另外：SDS不好溶解建议加热溶解,如果要做非还原SDS-PAGE请将2-巯基乙醇 0.5ml换成超纯水即可
电泳缓冲液的另一个作用是使溶液具有一定的导电性，以利于DNA分子的迁移，例如，一般电泳缓冲液中应含有0.01-0.04mol/L的Na+离子，Na+离子的浓度太低时电泳速度变慢；太高时就会造成过大的电流使胶发热甚至熔化。
电泳缓冲液还有一个组分是EDTA，加入浓度为1-2mmol/L，目的是螯合Mg2+ 等离子，防止电泳时激活 DNA酶，此外还可防止Mg2+离子与核酸生成沉淀。
