Product Information

Immunogen

Purified tobacco class I chitinase. The preparation used is a mixture of two class I isoforms (Shinshi et al., 1990; van Buuren et al., 1992): 1) Chitinase A (CHN A) P08252 encoded by gene chn48 derived from the N. tomentosiformis ancestor of tobacco. 2) Chitinase B (CHN B) P24091 encoded by gene chn50 derived from the N. sylvestris ancestor of tobacco.

Host Rabbit
Clonality Polyclonal
Purity Total IgG. Protein G purified in PBS pH 7.4.
Format Lyophilized
Quantity 2 mg
Reconstitution For reconstitution add 100 ĩl of sterile water
Storage Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
Tested applications Co-Immunoprecipitation (IP) (Co-IP), Immunolocalization (IL), Western blot (WB)
Recommended dilution 8 µg/ml (WB)
Expected | apparent MW

35, 34 | 32 and 34 kDa

western blot detection using class I chitinase antibodies

 

Detection of tobacco chitinase I in ng loaded per respective well using anti-tobacco chitinase I antibodies. Primary antibodies have been used at 8 µg/ml.

Additional information

Additional information
Antibody is recognizing closely related tobacco class I isoforms: endochitinase A CHN-A (ca. 34 kDa) and endochitinase B CHN-B (ca. 32 kDa)
This antibody can be used as a marker of vacuolar contents Keefe et al. (1990). The effect of ethylene on the cell-type-specific and intracellular localization of β-1,3-glucanase and chitinase in tobacco leave. Plant 182: 43-51. 
Important note: For blocking 5 % skim milk in PBS without Ca++ should be used,This antibody is purified by affinity chromarography on Portein G

Background

Background

Pathogenesis-related (PR) proteins, are induced in response to the infection of plants with microbial pathogens. Combinations of glucanase I and chitinase I are potent inhibitors of fungal growth in vitro however precise mechanism of that is still not known.  Glucanase I  (PR-2) and chitinase I (PR-3) contribute to defense against fungal infection and are currently used as markers for innate immunity, and in particular the ethylene/jasmonate signalling pathway in pathogenesis.
