Recombinant Human KRAS Protein, His-tagged, Alexa Fluor 555 conjugated

• Cat.No.: KRAS-456HAF555
• Product Overview: Alexa Fluor 555 conjugated recombinant human KRAS (AAH13572.1) (Thr2-Cys185, natural variant Gly 12 Cys) was expressed with a polyhistide tag at the N-terminus.

Specification

• Source: E. coli
• Species: Human
• Tag: His
• Form: Lyophilized
• Molecular Mass: 23.3 kDa
• Protein length: 202
• N-terminal Sequence Analysis: Met
• Endotoxin: < 1.0 EU/ μg of the protein as determined by the LAL method.
