product information
Background

Cysteine (a non-essential amino acid) is a building block of antioxidant glutathione. With a thiol side chain, cysteine is an important structural and functional component of many proteins and enzymes.

Immunogen

synthetic L-Cysteine conjugated to protein carrier (PC)

Host Rabbit
Clonality Polyclonal
Clone
Purity Total IgG purified by ammonium sulfate precipitation
Format Lyophilized present in PBS pH 7.35
Quantity 100 ĩl
Reconstitution For reconstitution add 50 ĩl of sterile water and 50 ĩl of glycerol
Storage

store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.

Tested applications immunocytochemistry (ICC)

Compounds Cross-reactivity ratio (a)
   
L-Cysteine-G-(Pc) 1
DL-Homocysteine-G-(Pc) 1/10
L-Methionine-G-(Pc) 1/>1 000
L-Glutathion-G-(Pc) 1/>1 000
L-Cysteic acid-G-(Pc) 1/>1 000
L-Serine-G-(Pc) 1/>1 000
Free L-Cysteine 1/>10 000

(a) : L-Cysteine-G-(Pc) concentration/unconjugated or conjugated close-related compounds concentration at half displacement ; G =Glutaraldehyde. Cross-reactivity ratios were evaluated by competitive ELISA: a ratio of 1/1000 means that 1000 times higher concentration of immunogen is needed to switch off the specific signal by half.

Additional information

example of immunohistochemical protocol can be found here.

Free cysteine will not attach to polystyrene ELISA plates. BSA-conjugated cysteine has to be used for this purpose.
