| Galectin-1

Galectin-1 is a protein that is encoded by the LGALS1 gene.It is 135 amino acids in length and highly conserved across species. It can be found in the nucleus, the cytoplasm, the cell surface and in the extracellular space. Galectins in general lack a traditional signal sequence, but are still secreted across the plasma membrane. This non-traditional secretion requires a functional glycan binding site. It contains a single carbohydrate recognition domain through which it can bind glycans both as a monomer and as a homodimer. Dimers are non-covalently bound and will spontaneously disassociate in low concentration.It does not bind glycans when oxidized.
 

| Typical data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

 

Concentration (ng/mL)	200	100	50	25	12.5	6.25	3.12	0
OD	2.15	1.46	0.87	0.6	0.39	0.28	0.21	0.09
Corrected OD	2.06	1.37	0.78	0.51	0.3	0.19	0.12	-

 

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Mouse Galectin-1 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Serum(n=8)	87-101	96
Plasma(n=8)	92-105	102
Cell Culture Supernates(n=8)	96-109	104

 

| Linearity

Samples were spiked with high concentrations of Mouse Galectin-1 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	84-95	88-96	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-102	87-108	105-115
	Average (%)	94	98	108
