Protein expression systems make it very easy to sensitively detect various proteins used widely in bioanalytics and molecular biology. Fluorophores or certain vitamins are used to tag antibodies or other proteins, and these labeled molecules can then be purified or detected using other solutions such as streptavidin or monomeric avidin. These protein expression systems are optimized for the rapid synthesis of functionally active proteins.

Catalog Number: (89139-626)
Supplier: Biotium
Description: biotin-X cadaverine (90061), and biotin ethylenediamine (90057) can be coupled to carboxylic acids, DNA and other biomolecules.


Catalog Number: (89139-606)
Supplier: Biotium
Description: can be easily converted to the mixed anhydride form, which is more reactive than the succinimidyl ester and thus can be used to react with aromatic amines or sterically hindered amines.


Catalog Number: (89411-598)
Supplier: Biotium
Description: The Biotin SE Protein Labeling Kit includes everything required to label proteins with biotin. Sufficient for three labelings of 1 mg protein each.


Catalog Number: (89139-724)
Supplier: Biotium
Description: is a water soluble biotin derivative that can be readily coupled to thiols.


Catalog Number: (89139-632)
Supplier: Biotium
Description: MTSEA biotin-X selectively labels thiols in the cell surface under mild condition. The X-spacer should facilitate better biotin-avidin or streptavidin interaction than MTSEA biotin (90064).


Catalog Number: (89139-662)
Supplier: Biotium
Description: free base can be directly coupled to activated carboxylic acid groups without using an additional base. The X-spacer should facilitate better biotin-avidin or streptavidin interaction than biotin cadaverine free base (90079).


Catalog Number: (89139-618)
Supplier: Biotium
Description: Biotin ethylenediamine iodoacetamide is readily coupled to thiols.


Catalog Number: (89139-636)
Supplier: Biotium
Description: MTSEA biotin-XX selectively labels thiols in the cell surface under mild condition. The XX-spacer should facilitate better biotin-avidin or streptavidin interaction than MTSEA biotin (90064).


Catalog Number: (89139-658)
Supplier: Biotium
Description: is a water soluble biotin derivative with an amine group.


Catalog Number: (89139-726)
Supplier: Biotium
Description: is used to covalently attach biotin to a molecule with an aldehyde or ketone group. The aminooxy group reacts with an aldehyde or ketone group to form a stable oxime linkage in an neutral aqueous condition. The reaction is fast and can be accelerated by adding aniline as a catalyst.


Catalog Number: (89139-628)
Supplier: Biotium
Description: MTSEA biotin selectively labels thiols in the cell surface under mild condition.


Catalog Number: (89139-602)
Supplier: Biotium
Description: Biotin-X succinimidyl ester is readily coupled to a primary or secondary amine under mild conditions.


Catalog Number: (89139-630)
Supplier: Biotium
Description: MTSEA biotin (90064) is supplied in a 50 mg unit size.


Catalog Number: (89139-804)
Supplier: Biotium
Description: Like TS biotin ethylenediamine (92010) TS biotin-XX ethylenediamine is a highly selective thiol labeling probe. The XX spacer should facilitate better interaction between biotin and avidin or streptavidin.


Catalog Number: (10119-154)
Supplier: Biotium
Description: Tyramide biotin-XX conjugate is used for tyramide signal amplification, The deposited biotin molecules can be detected with any of our CF labeled streptavidin conjugates.


Catalog Number: (89139-660)
Supplier: Biotium
Description: free base can be directly coupled to activated carboxylic acid groups without using an additional base.
