Composition	Bead size (micrometer)	Loading	DMF	THF	MeOH	Tol.	H20	DCM	Application	Comments
Polystyrene	Styrene cross-linked with divinylbenzene	75 - 150	0.5 - 1.0	3	8	2	7	0	7	Routine and large scale synthesis	Most cost-effective but can fail on synthesis of difficult or long sequences
NovaSyn® TG	PEG grafted on polystyrene	90	0.2 - 0.3	5	6	4	5	4	5	Research scale medium to long peptides	Pressure resistant, thus ideal for continuous flow
NovaSyn® TGR	PEG grafted on polystyrene	90	0.2 - 0.3	5	6	4	5	4	5	Research scale medium to long peptides	Special formulation of NovaSyn TG resin which gives even better results for long peptides
PEGA	Polyacrylamide PEG copolymer	150 - 300	0.2 - 0.4	11	13	13	12	16	13	On-bead enzyme assays	Internal bead space accessible to many proteins
NovaGel™ (Champion)	PEG grafted on polystyrene	75 - 150	0.6 - 0.8	7	7.5	4	n/d	n/d	n/d	Synthesis of medium length peptides	High-loading and high PEG content make it ideal for preparing medium-length peptides in quantity
NovaPEG (Chemmatrix)	Polyethene cross-linked with PEG	75 - 100	0.4 - 0.6	8	n/d	9	n/d	11	13	Long or difficult peptides	Quality of long peptides excellent but yields often low
SpheriTide™	Polylysine cross-linked with sebacic acid	250 - 350	2.7 - 3.3	5	n/d	10	n/d	7	2	Large scale synthesis	Very high loading to swell ratio, thus saves on reagent and solvent usage
