Description

LQP-21 TFA (TLQP-21 Trifluoroacetate) is a VGF-derived peptide that activates the C3aR1 receptor through a folding-upon-binding mechanism.

Targets

C3aR1 receptor

In vitro
In vitro	TLQP-21 activates the cognate C3aR1 receptor leading to enhanced lipolysis in adipocytes and arginine 21 is essential for TLQP-21 lipolysis in 3T3L1 adipocytes.^[1]
Cell Research	Cell lines	3T3L1 adipocytes
	Concentrations	100 nM
	Incubation Time	3 h
	Method	3T3-L1 adipocytes differentiated on 6-well plates are first starved for 3 hours in KRH with 1% BSA, then incubate with TLQP-21 in the presence and absence of specific agonists/antagonists, suspended in KRH with 4% BSA. Following 3 hours of incubation at 37°C and 5% CO2, the media is collected and incubated at 60°C for 20 min to inactivate any residual enzymatic reaction activity. The cells are gathered for protein concentration or trypsinized for cell diameter and viability measurements.
