The sizes of biotin, digoxigenin, FITC, etc.

[Wasun Chantratita]

Dear Netters

	I am  now working on nonradioactive in situ hybridization, in 
situ PCR and FISH (Fluorescent in situ hybridization).

	I would like to know the MW and size (Diameter) of these following 
ligands:

                                             MW               Diameter
	
	1. Biotin molecule                  ----------        ----------   
	2. Digoxigenin molecule             ----------        ----------    
	3. Streptavidin molecule            ----------        ----------
	4. Avidine molecule                 ----------        ----------
	5. Alkaline phosphatase molecule    ----------        ----------
        6. Horseradish peroxidase molecule  ----------        ----------  	
        7. FITC                             ----------        ----------

	These information will be very useful for perfoming in situ 
hybridization techniques with various types of polynucleotide and 
oligonucleotide probes labeled with these nonradioisotope ligands.

	Once I obtain all the results, I will post here for you all.

Thankyou
