Alexa Fluor™ 488-Labeled Human CD4 Protein, His Tag

CD4, CD4mut, LEU3

Alexa Fluor 488-Labeled Human CD4 Protein, His Tag (CD4-HA225) is expressed from human 293 cells (HEK293). It contains AA Lys 26 - Trp 390 (Accession # AAH25782). It is the Alexa Fluor™ 488 labeled form of Human CD4, His Tag (Cat. No. LE3-H5228).

AF488

Excitation Wavelength: 488 nm

Emission Wavelength: 517 nm

The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with AF488 using standard chemical labeling method. The residual AF488 is removed by molecular sieve treatment during purification process.

The AF488 to protein molar ratio is 2-4.

>90% as determined by SDS-PAGE.

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
