Description
Clathrin is the major protein component in the coat formed around pits and vesicles involved in receptor-mediated endocytosis. Clathrin forms a non-covalently bound triskelion structure composed of three heavy chains (192 kDa each) and three light chains (23-25 kDa each). Each leg of the triskelion structure contains one heavy and one light chain. The three heavy chains forming the triskelion structure are attached at their respective proximal ends like spokes on a wheel. Clathrin heavy chain is composed of a terminal globular domain, a distal segment containing several areas sensitive to enzymatic cleavage, and a proximal segment which contains a light chain binding site. The proximal and distal domains are connected by a joint segment at which there is a sharp bend in the heavy chains of fully-assembled triskelia. Although the calculated molecular weight is 192 kDa, clathrin heavy chain migrates at approximately 180 kDa.

FITC, fluorescein isothiocyanate, is a fluorochrome with a molecular weight of 389 Da. FITC is sensitive to pH changes and photobleaching. Due to nearly identical excitation and emission properties but different spillover characteristics, FITC and Alexa Fluor® 488 cannot be used simultaneously. FITC is relatively dim and should be reserved for highly expressed markers whenever possible.
Preparation and Storage
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
The antibody was conjugated with FITC under optimum conditions, and unreacted FITC was removed.
Store undiluted at -20°C.
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Please refer to www.bdbiosciences.com/pharmingen/protocols for technical protocols.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
