Product Image
Description:   MTSEA biotin-XX (90066) is supplied in a 50 mg unit size.
Catalog Number: 89139-638
Supplier: Biotium



Quantity:
 
 
 
   
Product Image
Description:   is a highly selective thiol labeling probe. TS (thiosulfate) group is negatively charged and thus probes bearing a TS group are ideal for specifically labeling thiols exposed at the exterior cell surface because charged probes are less likely to enter cells.
Catalog Number: 89139-800
Supplier: Biotium



Quantity:
 
 
 
   
Product Image
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: 89139-632
Supplier: Biotium

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



Quantity:
 
 
 
   
Product Image
Description:   Biotin-PEO4-propionate succinimidyl ester is a water soluble biotin derivative that can be readily coupled to primary or secondary amines.
Catalog Number: 89139-644
Supplier: Biotium



Quantity:

Description:   MTSEA biotin-X (90065) is supplied in a 50 mg unit size.
Catalog Number: 89139-634
Supplier: Biotium



Quantity:
 
 
 
   
Product Image
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: 89139-662
Supplier: Biotium



Quantity:
 
 
 
   
Product Image
Description:   can be coupled to activated carboxylic acid or sulfonyl chlorides in the presence of a base or in a basic buffer.
Catalog Number: 89139-622
Supplier: Biotium



Quantity:
 
 
 
   
Product Image
Description:   Biotin-12 SE is an amine-reactive biotin derivative with a long spacer group. This product can be conjugated to AA-dUTP or AA-UTP to make biotin-16-dUTP or biotin-16-UTP, two important products used in genomic studies.
Catalog Number: 89139-668
Supplier: Biotium



Quantity:
 
 
 
   
Product Image
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: 89139-804
Supplier: Biotium



Quantity:
 
 
 
   
Product Image
Description:   Biotin-X-C5-maleimide is readily and selectively coupled to thiols.
Catalog Number: 89139-616
Supplier: Biotium



Quantity:
 
 
 
   
Product Image
Description:   is a water soluble biotin derivative that can be readily coupled to activated carboxylic acids.
Catalog Number: 89139-640
Supplier: Biotium



Quantity:
 
 
 
   
Product Image
Description:   Biotin BCN(Biocyclo[6.1.0]nonyne), an alternative to biotin labeled DIBO and DBCO, reacts with azide to form 1, 2, 3-triazole by copper free 1,3-dipolar Huisgen cycloaddition. This copper free bioorthogonal reaction allows staining the surface of live cells with copper in cell extracts
Catalog Number: 10119-224
Supplier: Biotium



Quantity:
 
 
 
   
Product Image
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: 89139-726
Supplier: Biotium



Quantity:
 
 
 
   
Product Image
Description:   Like TS biotin ethylenediamine (92010) TS biotin-X ethylenediamine is a highly selective thiol labeling probe. The X spacer should facilitate better interaction between biotin and avidin or streptavidin.
Catalog Number: 89139-802
Supplier: Biotium



Quantity:
 
 
 
   
Product Image
Description:   biotin-X cadaverine (90061), and biotin ethylenediamine (90057) can be coupled to carboxylic acids, DNA and other biomolecules.
