Animal-Free Laminin 521 蛋白, Human

目录号: HY-P701311AF
COA 产品使用指南

Laminins are a major component of basement membranes. Laminin 521 is a heterotrimeric glycoprotein composed of one α5, one β2, and one γ1 chain, is a defined matrix for feeder-free culture of human embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs). When used in combination with defined maintenance media, Laminin 521 reliably facilitates self-renewal of human ESCs and iPSCs without spontaneous differentiation.

无动物成分 (Animal-free) 重组蛋白，即生产过程中不使用或接触任何动物来源的材料和试剂，具有高一致性和稳定性。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
