gBlocks™ Gene Fragments are double-stranded DNA fragments of 125–3000 bp in length. They are the industry standard for double-stranded gene fragments, designed for affordable and easy gene construction or modification, applications such as antibody research and CRISPR-mediated genome editing, qPCR standards, and more.

What are gBlocks used for?
gBlocks Gene Fragments have been used in a wide range of applications including CRISPR-mediated genome editing, antibody research, codon optimization, mutagenesis, and aptamer expression. They can also be used for generating qPCR standards.
How do gBlocks work?
How the method works. Gblocks selects conserved blocks from a multiple alignment according to a set of features of the alignment positions. First, the degree of conservation of every positions of the multiple alignment is evaluated and classified as nonconserved, conserved, or highly conserved.
What is a gene fragment?
Gene fragments are pieces of genes containing only the exons (those parts of the gene which actually encode the protein sequence). They are composed of cDNA.
Are gBlocks methylated?
gBlocks Gene Fragments and PrimeTime qPCR Assays support simple methylation analysis method.
How do you optimize a codon?
Obtain results in one of the following ways:
- Use default optimization rules. Click on Optimize (lower right orange button).
- To manually optimize your original sequence, click on Map Codons Only and then Manual Optimization (Figure 2) to change codon usage for any amino acid or stop codon in your sequence (Figure 3).
What is the significance of trimming sequences after alignment?
The idea with the trimming is to remove noisy regions. Homologous proteins can contain regions that are not inherited and should therefore not be aligned, and other regions may have evolved so fast that the correct multialignment is impossible to infer.
What is est in bio?
expressed sequence tag (EST)
What are DNA fragments called?
A restriction fragment is a DNA fragment resulting from the cutting of a DNA strand by a restriction enzyme (restriction endonucleases), a process called restriction. Restriction fragments can be analyzed using techniques such as gel electrophoresis or used in recombinant DNA technology.
Do plasmids replicate?
The plasmid is a small DNA molecule within a chamber that is physically separated from chromosomal DNA and can replicate independently .
How does methylation analysis work?
Methylation analysis is the study of chromosomal patterns of DNA or histone modification by methyl groups. Methylation constitutes an epigenetic mark because its location can affect the regulation of gene expression in a heritable fashion.
How do you calculate methylation percentage?
Methylation percentage is then calculated from the ratio of heights of a cytosine peak (methylated signal) and the sum of cytosine and thymine peaks (methylated and unmethylated signal) for each cytosine in a CpG dinucleotide. As mentioned above, this method is suitable for regions 80–200 bp long.
What is a methylation analysis test?
view test catalog. Methylation analysis provides important information about the inactivation and regulation of DNA sections, associated with various disorders, which might go undetected when using only sequencing analyses or fragment length-based techniques.
