| Biotin Actin   Biotin Actin-Conjugates Ready-to-use, instant solubility.     
   Biotin-actin conjugates are used to investigate actin interactions in-vitro assays.  Biotin-actin from skeletal or cardiac muscle α-actin are prepared by labelling lysine residues of actin with  activated Biotin-esters. The advantage of this Biotin-actin is the non-cleavable 22 angstroms spacer arm,  making the protein readily available for detection.    Applications  Elisa asays, Motility assays, Microinjection, Pull-down assays     Biotin-Actin (alpha-actin, rabbit skeletal muscle)   Description | Protein |   | Biotin-Actin |  | Origin |   | Skeletal muscle alpha actin, rabbit |  | Molecular mass |   | 42kDa |  |   Protein description     |   |   Biotin-Actin from rabbit skeletal muscle is chemically modified α-actin by esterification of lysine residues with biotin.   |  |   Conjugation ratio   |   |   The degree of labelling (DOL) of Biotin-Actin is approx. 1:1 (biotin:actin)   |
